Which of the following statements about metabolism is correct?
AMetabolism only involves energy production
BMetabolism is the ability to respond to stimuli
CMetabolism is the process of producing offspring
DMetabolism includes both anabolic and catabolic reactions
Step-by-Step Solution
Step 1: Understand metabolism
Metabolism is the sum of all chemical reactions in an organism.
Step 2: Analyze options
Energy production is part of metabolism but not all. Producing offspring is reproduction. Responding to stimuli is a different characteristic. Metabolism includes anabolic (building) and catabolic (breaking down) reactions.
Step 3: Why other options are wrong
Only stating energy production ignores synthesis reactions. Reproduction and response to stimuli are separate processes.
Final Answer:
Metabolism includes both anabolic and catabolic reactions → Option D
Quick Check:
Metabolism = Anabolic + Catabolic reactions ✅
Quick Trick:Metabolism = building + breaking reactions.
Common Mistakes:
Thinking metabolism is only energy release.
