<h2>TCA cycle </h2>

Explanation:

TCA or citric acid cycle is an oxidative pathway which occurs in matrix of mitochondria that completely oxidize Acetyl CoA in form of CO2 and produce NADH, FADH2 and GTP

The aim of this cycle is to fulfill the energy demand of cell

In the first step of the cycle, Acetyl CoA combines with a four-carbon acceptor molecule, oxaloacetate, to form a six-carbon molecule called citrate

After a quick rearrangement, this six-carbon molecule releases two of its carbons as carbon dioxide molecules in a pair of similar reactions, producing a molecule of NADH each time

The enzymes that catalyze these reactions are key regulators of the citric acid cycle, speeding it up or slowing it down based on the cell’s energy needs

The remaining four-carbon molecule undergoes a series of additional reactions, first making an ATP molecule—or, in some cells, a similar molecule called GTP—then reducing the electron carrier FAD to FADH2 and finally generating another NADH; This set of reactions regenerates the starting molecule, oxaloacetate, so the cycle can repeat

Overall, one turn of the citric acid cycle releases two carbon dioxide molecules and produces three NADH, one FADH2, one ATP or GTP

The citric acid cycle goes around twice for each molecule of glucose that enters cellular respiration because there are two pyruvates—and thus, two Acetyl CoA made per glucose

Answer:

Nutrient cycle is a process  of movement, reuse or recycling of nutrients in that particular environment. They are for both living and nonliving things, elements like carbon, oxygen are recycled through such cycles.

Nutrient cycle in an ecosystem involve:

  • carbon cycle
  • nitrogen cycle
  • oxygen cycle

How can the ethiopian wolves prey be classified as.<br><br> Dont say endangered plz
TEA [102]

Given what we know about the diet of the Ethiopian wolves, we can confirm that their prey can be classified as rodents.

<h3>What are Ethiopian wolves?</h3>
  • The Ethiopian wolves are a canine native to Ethiopia.
  • They are carnivores and hunt in packs.
  • Despite their name, they more closely resemble foxes or jackals.
  • They feed on rodents such as rats and hares.

Therefore, given their diet based primarily on animals such as hares, giant mole rats, and grass rats, we can confirm that the prey of the Ethiopian wolves can be classified as rodents.

2a) Which of the following statements about pyruvate oxidation IS TRUE?
Darina [25.2K]

The true statements are:

  • Substrate level phosphorylation ocvurs during Pyruvate oxidation
  • 32 ATP molecules can be made by cellular respiration but only 2 ATP molecules when oxygen is lacking
  • Electrons move from protein to protein due to increasing electronegativity in the electron transport chain
  • ADP is phosphorylated in the matrix of the mitochondria during oxidative phosphorylation
  • ATP inhibits pyruvate dehydrogenase by feedback inhibition

<h3>What is glucose oxidation?</h3>

Glucose oxidation refers to the process in the cells in which glucose molecules are oxidized to form ATP and carbon dioxide in the presence of oxygen.

The first stage of glucose oxidation is the conversion to pyruvate.

Pyruvate is oxidized to acetylCoA.

AcetylCoA enters the citric acid cycle to produce reducing equivalents, NADH for the electron transport chain.

  • The true statements about pyruvate oxidation is that there is substrate level phosphorylation during the process
  • When there is sufficient oxygen, 36 ATP molecules can be made (theoretically) by cellular respiration. However, when oxygen is lacking, only 2 ATP molecules are made.
  • In the electron transport chain of cellular respiration, electrons move from protein to protein due to increasing electronegativity
  • During oxidative phosphorylation, ADP is phosphorylated in the matrix of the mitochondria
  • Aerobic respiration can be regulated by feedback inhibition of pyruvate dehydrogenase by ATP.
