What is it called when a reaction needs oxygen?

Back

aerobic, aerobic respiration, In the mitochondria

Answer explanation

A reaction that requires oxygen is called aerobic. This term is often associated with aerobic respiration, which occurs in the mitochondria of cells, where oxygen is used to produce energy.

What is the net product for the Krebs cycle for each GLUCOSE molecule used? Options: 6 NADH, 2 FADH2, 4 CO2, 2 ATP, NADH, FADH2, CO2, ATP

Back

6 NADH, 2 FADH2, 4 CO2, 2 ATP

Answer explanation

The net product of the Krebs cycle per glucose molecule is 6 NADH, 2 FADH2, 4 CO2, and 2 ATP. Therefore, the correct answer is not 0, as it does not reflect the actual outputs of the cycle.

Why is the electron transport chain so important?

Back

It produces the most ATP, Makes 34 ATP

Answer explanation

The electron transport chain is crucial because it produces the most ATP during cellular respiration, generating approximately 34 ATP molecules, which is essential for energy supply in cells.

Front

What is the protein that makes the ATP in the electron transport chain?

Back

ATP synthase

Answer explanation

ATP synthase is the enzyme responsible for synthesizing ATP in the electron transport chain. It utilizes the proton gradient created by electron transport to drive the conversion of ADP and inorganic phosphate into ATP.

Front

What does ATP stand for?

Back

Adenine triphosphate

Answer explanation

ATP stands for Adenine triphosphate, which is a crucial molecule in cellular energy transfer. It serves as the primary energy carrier in all living organisms.

Front

What is the equation of cellular respiration?

Back

C6H12O6 +6O2 = 6CO2 + 6H2O +ATP, Glucose + Oxygen = Carbon dioxide + water + ATP

Answer explanation

The equation of cellular respiration shows that glucose (C6H12O6) and oxygen (O2) are converted into carbon dioxide (CO2), water (H2O), and ATP, which is the energy currency of the cell. Both forms of the equation are correct.
