The rate of demand for energy in the body determines whether the body will use aerobic or

Gwar [14]3 years ago

Explanation:

Isabella: 50-meter freestyle - inadequate oxygenation over a short period of time

  • anaerobic cellular respiration
  • incomplete breakdown of glucose waste products: lactic acid  
  • traps 2 molecules of ATP for each gram of glucose

Tyler: half marathon- adequate oxygenation of tissue over a long period of time

  • aerobic cellular respiration
  • complete breakdown of glucose
  • traps 36 molecules of ATP for each gram of glucose
  • waste products: H2O, CO2

Further Explanation:

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

  • Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
  • The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
  • The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

Within cells, aerobic respiration may not occur due to several factors:

  • - a lack of inorganic, final electron acceptors
  • -incomplete or lack of a complete electron transport system
  • -missing genes for enzymes within the Kreb's cycle

Thus, they utilize other means for the generation of energy in the form of ATP and to replenish NAD+, an oxidized form of NADH, the main electron carrier in glycolysis. Pyruvate is produced in the cytoplasm via glycolysis- it is also used as an electron acceptor in a process called fermentation.

Taxonomy

The Radio-ulna and digits of most primates and animals represents a homologous structure




An example of another internal structure is the genes.
The homologous chromosomes have the same genes in common. Each cell has at least two sets of chromosomes which one comes from one’s father also called as paternal chromosome and mother, called as the maternal chromosomes. These chromosomes are what makes the child obtain the characters and may depend on the traits the parents possess. Homologous chromosomes are not duplicated chromosomes or identical however, they are analogous or similar. The alleles for a specific characteristics isn’t the same but the same genes are in the same order.<span> </span>

As you may know, people’s physical and emotional health interact: One can affect the other. The characters in "In Another Countr
Margaret [11]

Answer:

To preserve their mental health, the characters must keep in mind that all suffering is temporary and although it is difficult, they will overcome this situation. What can help characters deal with their situations is by reasoning about the following questions:

"What led me to this situation?"

"What are my limitations in dealing with this type of problem?"

"How could I have acted to minimize the impacts of suffering?"

"Would any action by me prevent these disorders?"

Explanation:

Every time that the characters evaluate themselves and correct their behaviors, they will be able to follow the emotional evolution that will help them to deal with all their suffering. In this journey, each one has a different rhythm. In fact, we are different in almost every aspect of our physical and mental makeup. The variations in intelligence are enormous and also those related to aggressiveness, intensity of fears and the ability to deal with them. It would not be fair, therefore, to tell a character (or a person) that he is suffering from "nonsense". What is small for one may be large for the other. Underestimating the pain of others is not synonymous with help, but a lack of empathy.

We do have a duty and obligation, in the name of our own well-being, to try to get rid of our pains as quickly as possible, but that does not mean not feeling them. Some people do it more easily, while others "fall in love" with the problem and think about it in a recurrent and obsessive way. They silence the word, but the mind goes on chattering.

What temperature pattern do the isotherms show? temperatures increase from south to north. there is a zone of low temperatures i
777dan777 [17]

The temperature pattern which is being shown by the isotherms is that: D. temperatures increase from the center of the country toward the Southwest.​

<h3>What is an isotherm?</h3>

An isotherm refers to a line that is drawn on a map to join points that are having the same temperature, in order to show the distribution of temperature in a geographical area on Earth's surface.

Based on the weather map in the image attached below, we can infer and logically deduce that temperatures typically increase from the center of the country toward the Southwest.​
