Bio Unit 5 - Lesson 1: Cell Respiration

Multiple Choice

Why is ATP considered the energy currency of the cell?

• Because it stores genetic information

• Because it provides energy for cellular processes

• Because it is a structural component of cell membranes

• Because it transports oxygen in the blood

Multiple Choice

Which of the following is a correct description of cell respiration?

• A process where cells divide to produce energy

• A chemical reaction where organic molecules are transformed into energy

• A process where oxygen is converted into glucose

• A reaction that only occurs in mitochondria

Multiple Choice

What are the main reactants and products of aerobic cellular respiration as shown in the formula?

• Glucose and oxygen; carbon dioxide, water, and energy

• Glucose and carbon dioxide; oxygen and water

• Oxygen and water; glucose and carbon dioxide

• Glucose and ATP; oxygen and water

Fill in the Blanks

During cell respiration, NAD+ is converted to

when it gains electrons.

Multiple Select

Which of the following are products of the Krebs Cycle?

• NADH

• ATP

• CO2

• FADH2

Fill in the Blanks

During oxidative phosphorylation, hydrogen atoms diffuse through an ATP factory called

Synthase.

​

Multiple Choice

Which stage of cellular respiration produces the most ATP?

• Glycolysis

• Pyruvate Oxidation

• Krebs Cycle

• Oxidative Phosphorylation

Multiple Choice

Which of the following is the correct sequence of stages in cellular respiration?

• Glycolysis → Krebs Cycle → Pyruvate Oxidation → Electron Transport Chain

• Glycolysis → Pyruvate Oxidation → Krebs Cycle → Electron Transport Chain

• Krebs Cycle → Glycolysis → Pyruvate Oxidation → Electron Transport Chain

• Pyruvate Oxidation → Glycolysis → Krebs Cycle → Electron Transport Chain
