In the Darfur region of the Sudan, Arab herders and African farmers have survived on the same land for generations. Although the

y live off the same land, their different histories and traditions led them to make different cultural adaptations (i.e., farming versus herding) for survival. The difference in livelihoods between the groups suggests what about culture and the physical environment?

When oxygen is plentiful inside a skeletal muscle cell, what happens to the pyruvic acid that is formed during glycolysis?
Iteru [2.4K]

Answer:

d. it diffuses into mitochondria to be broken down to generate ATP

Explanation:

When enough oxygen is available in the muscle cells, pyruvate produced by glycolysis enters the mitochondrial matrix. Once inside the mitochondria, pyruvate is decarboxylated into acetyl CoA. The reaction is catalyzed by the enzyme complex pyruvate dehydrogenase. Acetyl CoA then enters a sequence of reactions called Kreb's cycle and is broken down into CO2 and H2O. The energy released during these reactions is stored in the form of NADH and FADH2.

The NADH and FADH2 are oxidized by giving their electrons to O2 via electron transport chain. During this oxidation, the proton concentration gradient is generated across the inner mitochondrial membrane which in turn drives the process of ATP synthesis.

What two compounds are the waste products of cellular respiration? * H2O and CO2 H2O and C6H12O6 CO2 and C6H12O6 ATP and CO2
rusak2 [61]

Answer:

The two compounds that correspond to waste products of cellular respiration are H₂O and CO₂.

Explanation:

The cellular metabolic waste products, specifically from cellular respiration are water (H₂O) and carbon dioxide (CO₂), from the oxidation of glucose into energy.

The process of <u>cellular respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions</u> where, from a glucose molecule, energy is obtained in the form of ATP molecules.

Obtaining H₂O and CO₂ from glucose can be summarized with the schematic reaction:

                                 <em>C₆H₁₂O₆  +  6O₂ →  6H₂O  +  6CO₂</em>

This summary indicates that a glucose molecule, when oxidized, produces as waste 6 molecules of water and 6 molecules of carbon dioxide. To reach this process all the reactions of the oxidative phosphorylation occur and 24 molecules of ATP are obtained for each molecule of glucose.

For the other options it is important to mention that:

  • <em><u>C₆H₁₂O₆</u></em><em> is the substrate from which cellular respiration takes place. </em>
  • <em><u>ATP </u></em><em>is the final product of cellular respiration, translated into energy to be used by the cell.</em>
