Cellular Respiration

What is Adenosine Triphosphate (ATP) primarily known for in cells?

• Building cell walls

• Storing and transferring energy

• Transporting genetic information

• Forming the cell membrane

Which of the following best describes aerobic cellular respiration?

• A process that creates glucose from carbon dioxide and water.

• A metabolic process that breaks down glucose using oxygen to produce ATP.

• A process that occurs only in prokaryotic cells.

• A process that does not require oxygen.

What are the primary reactants required for aerobic cellular respiration?

• Carbon dioxide and water

• Glucose and oxygen

• ATP and light

• Pyruvate and NADH

Which statement accurately describes glycolysis?

• It requires oxygen and occurs in the mitochondria.

• It breaks down two pyruvate molecules into one glucose molecule.

• It is an anaerobic process that occurs in the cytoplasm.

• It results in a net gain of 4 ATP molecules.

Are you enjoying the video lesson?

• Yes

• No

What are the net products generated during the first step of glycolysis?

• One glucose molecule, two ATP, and two NADH

• Two pyruvate molecules, a net gain of two ATP, and two NADH

• Four ATP molecules, two pyruvate, and two FADH2

• One Acetyl CoA molecule, carbon dioxide, and two NADH

What is the fate of pyruvate molecules after they are actively transported into the mitochondrial matrix?

• They are directly converted into glucose for energy storage.

• They undergo oxidation, transforming into Acetyl CoA, with the release of carbon dioxide and NADH.

• They are immediately used to synthesize FADH2 for the electron transport chain.

• They combine with oxygen to produce water and ATP.

Which energy-carrying molecules are produced during the Krebs Cycle?

• Glucose, water, and oxygen

• Pyruvate, ATP, and FADH2

• ATP, NADH, and FADH2

• Acetyl CoA, carbon dioxide, and water

In eukaryotic cells, where is the Electron Transport Chain located?

• The cytoplasm

• The outer mitochondrial membrane

• The inner mitochondrial membrane

• The nucleus
