Question

question 1-49
a student creates a flowchart to model the release of energy from glucose in an animal cell.
flowchart: glucose → glycolysis; glycolysis → 1.__ → lactic acid; glycolysis → 2.__ → co₂ + h₂o
which of the following best completes the missing portions of the flowchart?
options:
1: aerobic respiration, 2: anaerobic respiration
1: anaerobic respiration, 2: aerobic respiration
1: evaporative photosynthesis, 2: transpiration
1: transpiration, 2: evaporative photosynthesis

Explanation:

Step1: Recall respiration types

Anaerobic respiration (no oxygen) in animal cells produces lactic acid. Aerobic respiration (with oxygen) produces \(CO_2 + H_2O\).

Step2: Match with flowchart

1. leads to lactic acid → anaerobic respiration. 2. leads to \(CO_2 + H_2O\) → aerobic respiration. Eliminate options with photosynthesis/transpiration (plant processes).

Answer:

1: Anaerobic respiration, 2: Aerobic respiration
