How does the amount of oxygen affect cellular respiration?

High oxygen levels allow cells to do aerobic respiration, which requires oxygen to make ATP and produces more ATP than in the absence of oxygen, called anaerobic respiration.

What is exact role of oxygen in respiration?

Oxygen plays a vital role in energy production via a system called electron transport chain (ETC), which is an important component of cellular respiration. Oxygen acts as a final electron acceptor that helps move electrons down a chain that results in adenosine triphosphate production.

How would you compare the summary equation of photosynthesis and respiration?

Connecting Cellular Respiration and Photosynthesis The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.

What effect would an absence of oxygen o2 have on the process of oxidative phosphorylation the electron transport chain )?

Oxidative phosphorylation would eventually stop entirely, resulting in no ATP production by this process. Without oxygen to “pull” electrons down the electron transport chain, H+ would not be pumped into the mitochondrion’s intermembrane and chemiosmosis.

Why is oxygen reduced in cellular respiration?

The Net Chemical Reaction The overall chemical reaction of cellular respiration converts one six-carbon molecule of glucose and six molecules of oxygen into six molecules of carbon dioxide and six molecules of water. So the carbons in the glucose become oxidized, and the oxygens become reduced.

How does oxygen get into the cell in order for cellular respiration to occur?

As ATP is needed for the cells to function properly, every cell in your body needs oxygen. Getting that oxygen begins with inhaling. The oxygen moves into your blood, where it travels to every cell in your body. How many CO molecules can I get with one molecule of glucose in the process of cellular respiration?

Why is oxygen needed in cellular respiration quizlet?

Why is oxygen needed for cellular respiration? Oxygen is used to bond with hydrogen to form water. NADH and FADH2 are made. Intermediate molecule with CoA (enzyme) enters the Krebs Cycle.

What is the role of oxygen in respiration quizlet?

What is the role of oxygen in cellular respiration? Oxygen accepts high-energy electrons after they are stripped from glucose. Cellular respiration accomplishes two major processes: (1) it breaks glucose down into smaller molecules, and (2) it harvests the chemical energy released and stores it in ATP molecules.

What roles does oxygen play in photosynthesis and in cellular respiration?

What roles does oxygen play in photosynthesis and in cellular respiration? Photosynthesis releases oxygen into the atmosphere as a. product, whereas cellular respiration uses oxygen as a reactant to release energy from food.

Does cellular respiration require oxygen?

Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.

What effect would the absence of oxygen have on the process shown above?

What effect would an absence O2 have on the process shown in Figure 7.14? Oxidative phosphorylation would eventually stop entirely, resulting in no ATP production by this process.

What effect would an absence of O2 have on the process?

In the absence of oxygen, a cell will go through anaerobic respiration and a process called fermentation. Occurs in yeast when oxygen is not available. If oxygen is present, then the cell will go through a two-step process known as aerobic respiration to obtain energy. You get more ATP.

How many molecules of oxygen are produced during cellular respiration?

During cellular respiration, one glucose molecule combines with six oxygen molecules to produce water, carbon dioxide and 38 units of ATP. The chemical formula for the overall process is:

What would happen if there was no oxygen for aerobic respiration?

In aerobic respiration, one molecule of glucose is broken down to produce 34 to 36 molecules of ATP, the energy currency of the cell. If there was no oxygen available, aerobic respiration would stop and organsims that rely on aerobic respiration would die.

How do you get 18 oxygen atoms from 12 oxygen atoms?

In order to get 18 oxygen atoms on the reactant side you need an additional 12 oxygen atoms from oxygen #O_2# to balance the numbers. The process of cellular respiration will produce 36 ATP molecules in Eukaryotes (plant/animal etc.) for every one glucose molecule.

What would happen if there was no oxygen in a cell?

Aerobic respiration requires oxygen. In aerobic respiration, one molecule of glucose is broken down to produce 34 to 36 molecules of ATP, the energy currency of the cell. If there was no oxygen available, aerobic respiration would stop and organsims that rely on aerobic respiration would die.
