1.Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. The chemical equation is C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water).

2.Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions.

3.A fundamental task of proteins is to act as enzymes—catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.

4.Aerobic respiration is characteristic of eukaryotic cells when they have sufficient oxygen and most of it takes place in the mitochondria.

5.The end product of anaerobic respiration is lactic acid instead of carbon dioxide and water. ... Hence, the amount of oxygen required to oxidize lactic acid to carbon dioxide and water is not present. Aerobic respiration produces 38 ATP whereas anaerobic respiration produces only 2 ATP molecules.

6.Anaerobic respiration occurs when the amount of oxygen available is too low to support the process of aerobic respiration. There are two main types of anaerobic respiration, alcoholic fermentation and lactic acid fermentation.

7.The end products of anaerobic respiration are Lactic acid or ethanol and ATP molecules. Anaerobic respiration takes place in the absence of oxygen and is seen in lower animals. During the process of Anaerobic Respiration in prokaryotes, there is a breakdown of glucose to produce energy for cellular activities.

8.Complete double ciruculatory systems allow for higher metabolic rates to be maintained as there is no mixing of oxygenated and deoxygenated blood. This means that blood leaving the heart to travel to the body is rich in oxygen.

9.ATP functions as the energy currency for cells. It allows the cell to store energy briefly and transport it within the cell to support endergonic chemical reactions. The structure of ATP is that of an RNA nucleotide with three phosphates attached.

10.Muscles cells contain more mitochondria because they have to release large amount of energy quickly for movement.

11.Carbohydrate loading is a type of diet where foods high in carbohydrates are eaten a few days prior to or right before an event; this is believed to help aid and provide energy during long- term endurance events. ... Carbohydrates are broken down by the body and turned into glycogen; which is stored in muscles.

12.Aerobic respiration takes place in presence of oxygen; whereas anaerobic respiration takes place in absence of oxygen. Carbon dioxide and water are the end products of aerobic respiration, while alcohol is the end product of anaerobic respiration. Aerobic respiration releases more energy than anaerobic respiration.

13.More blood is pumped to the exercising muscles to deliver that additional O. Without enough oxygen, lactic acid will form instead. Lactic acid is typically flushed from the body within 30 to 60 minutes after finishing up a workout. Tiny tears form in the muscles that help them grow bigger and stronger as they heal

14.The overall process of glycolysis is: Glucose + 2 NAD+ + 2 ADP + 2 Pi → 2 pyruvate + 2 NADH + 2 H+ + 2 ATP.

15.During these times, your respiratory and cardiovascular systems cannot transport oxygen to your muscle cells, especially those in your legs, fast enough to maintain aerobic respiration. To allow the continuous production of some ATP, your muscle cells use lactic acid fermentation.

What areas can Exosome be used in? What does it do?

Answer:Exosomes as Diagnostic Biomarkers

Exosomes are membrane vesicles secreted by all types of cells and are also discovered in the body fluids such as: saliva, blood, urine and breast milk. Exosomes are unique because its protein, lipid, RNAs contents provide additional hint for their identification. Therefore, exosomes have been considered as accessible diagnostic biomarkers with great potential for detection of many pathological conditions, including cancer.

Identification and quantitation of exosomes as well as its proteins, lipids, RNAs contents become useful tools for diagnostic purposes. More than 4400 different proteins have been identified to be associated with exosomes by mass spectrophotometer. Besides, exosomes are also enriched with different lipids like cholesterol, sphingolipids, phosphoglycerides, ceramides, etc. To detect disease in early stages, the PCR of miRNA is a new promising approach to detect RNA in patients’ serum.

Exosomes as Therapeutic Target

Given the fact that elevated exosome levels are often correlated with greater severity of different types of cancer, reducing circulating exosomes to normal levels is one of therapeutic strategies to increase treatment efficacy. There are different approaches to modulate exosome production: 1) Inhibition of exosome formation: inhibit crucial proteins involved in exosome formation pathway; 2) Inhibition of exosome release: inhibit important regulators of exosome release process, increased intracellular Ca2+, change cellular microenvironmental pH; 3) Inhibition of exosome uptake: add proteinase for surface proteins on exosomes may serve as receptors for uptake pathways. In addition to control exosomes production, removal of exosomes from the entire circulatory system might be a novel strategy for cancer treatment.

Exosomes could also be used as cancer immunotherapy becasue tumor-derived exosomes carry antigens that is a great source of specific stimulus for the immune response against tumors. Both tumor-derived and dendritic cell-derived exosomes have showed capability to stimulate tumor antigen-specific responses in experimental animal models and human clinical trials.

Exosomes as Targeted Drug Delivery Vehicles

Exosomes became one of the most common methods applied in drug delivery system because of several advantages they have. Firstly, exosomes normally have a small size 40-100 nm, which is more homogenous compared to other microvesicles. This will lead them to evade rapid clearance by the mononuclear phagocyte and enhances passage through fenestrations in the vessel wall. Secondly, due to their endogenous origin, they are less toxic for and better tolerated by the immune system. It facilitates them to avoid causing side effects that normally occur with synthetic nanoparticles. Additionally, the specific ligand or protein expressed on the exosome surface increases efficiency of cargo into the cytosol of the target cell, and therefore fewer off-target effects. Exosomes are generally found most useful as a drug delivery medium in cancer therapy, anti-inflammation and gene interference therapy such as transferring of miRNA.

Using all three parts of the cell theory explain why something would be considered living
Viktor [21]
<span>The cell theory is an explanation of what cells are and why they exist.  The three main parts are:  1) All living things are made of cells and their products,  2) New cells are created by old cells dividing into two, and  3) Cells are the basic building units of life.  In 1665, Robert Hooke observed, with the aid of a crude compound microsope, the structure of a thin slice of cork.  The structure resembled stacks of hat boxes, or holding cells, so he called what he observed "cells".  In 1674, Anton von Leeuenhoek observed, in a sample of pond water, small animal-like creatures swimming around.  He probably was looking at Spyrogira, but he called these small organisms "animal-cules".  Theodore Schwann and Matthias Schleiden are responsible for formulating the first two parts of the cell theory, which was a scientific explanation of what these scientists had observed up to this point.  A few years later, Rudolph Virchow added the third part of the cell theory, that all things are composed of these basic building blocks called cells.</span>

Answer:

Your answer would be a autosomal dominant disorder.

____________________________________________________

Definition:

Autosomal Dominant Disorder:

A disorder in which could pass a disease from generations and on. In other words, future generations "inherit" the disease

____________________________________________________

Explanation:

The reason why "autosomal dominant disorder" is the correct answer because when a disease has been going on for many generations, this would be known as an autosomal dominant disorder, or ADD. What this means is that a person could have a mutant gene in them, also having a normal gene that is paired with  autosomal chromosomes. These diseases are inherited from a off spring that could take the disease and pass it on to their off springs, which would go on for generations due to the fact that it is a "dominant" trait. This is similar to the autosomal recessive disorder, but the autosomal recessive disorder needs two mutant genes in them, meaning that there is a less likely chance of getting the disease passed on to the off spring. The autosomal dominant disorder only needs one mutant gene in order to be effective during the inheritance for a offspring.
