Cellular Respiration, please help this is due tomorrow and I don't get it at all.
saw5 [17]

Answer:

What does cellular respiration due?

<h2>Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.</h2>

Explanation:

<h2>What are the 7 steps of cellular respiration in order?</h2>

<h2>Overview of the steps of cellular respiration. Glycolysis. Six-carbon glucose is converted into two pyruvates (three carbons each). ATP and NADH are made.</h2>

...

<h2>Glycolysis. ... </h2><h2>Pyruvate oxidation. ... </h2><h2>Citric acid cycle. ... </h2><h2>Oxidative phosphorylation</h2>

<h2>Answer</h2>

<h2> Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules[1] or nutrients into adenosine triphosphate (ATP), and then release waste products.[2] The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen,[3] are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.Nutrients that are commonly used by animal and plant cells in respiration include sugar, amino acids and fatty acids, and the most common oxidizing agent providing most of the chemical energy is molecular oxygen (O2).[1] The chemical energy stored in ATP (the bond of its third phosphate group to the rest of the molecule can be broken allowing more stable products to form, thereby releasing energy for use by the cell) can then be used to drive processes requiring energy, including biosynthesis, locomotion or transport of molecules across cell membranes.</h2>

Suppose a population is carrying a condition controlled by two alleles: A (dominant) and a (recessive). Only homozygous individu
statuscvo [17]

Let a be Q, all which is homozygous recessive = Q∧2

A = p, AA which is homozygous recessive = Q∧2


2pq = heterozygous

It is derived from p+ q = 1

All those in a population which is Q = 20%


All A in the population (p) = 80%

Now that the disease is homozygous recessive therefore,

aa = qq or q × q = 0.20 × 2 = 4%

Then the answer is 4%.

inysia [295]

Answer:

Fossils consistently found in the same geologic time period allow us to infer that the organisms whose fossils are found were prevalent/widespread to a certain extent during that time period.
