Sample Questions and Answers from a Cellular Respiration Worksheet
Below are examples of typical questions found in a cellular respiration worksheet along with their answers to illustrate the depth and type of content included.
Question 1: Multiple Choice
Which molecule is the primary energy carrier produced during glycolysis?
a) FADH2
b) NADH
c) ATP
d) Pyruvate
Answer: c) ATP
Explanation: Glycolysis produces a net gain of 2 ATP molecules directly, but also generates NADH which later contributes to ATP production during electron transport.
Question 2: Label the Diagram
Label the stages of cellular respiration in the diagram of a mitochondrion.
Answer:
- Glycolysis occurs in the cytoplasm (outside mitochondrion).
- The Krebs cycle takes place in the mitochondrial matrix.
- The electron transport chain is located in the inner mitochondrial membrane.
Question 3: Short Answer
Describe the role of oxygen in cellular respiration.
Answer:
Oxygen acts as the final electron acceptor in the electron transport chain. It combines with electrons and protons to form water. Without oxygen, the chain cannot function efficiently, leading to a halt in ATP production via aerobic respiration, which forces the cell to rely on less efficient anaerobic processes.
Question 4: Calculation Problem
If one molecule of glucose yields approximately 36 ATP molecules during cellular respiration, how many ATP molecules are produced from 3 molecules of glucose?
Answer:
3 molecules of glucose would produce approximately 3 × 36 = 108 ATP molecules.
