How is an analogy different from a metaphor

An analogy is a comparison between two things
Example: banana is to yellow as red is to apple OR banana:yellow as red:apple

A metaphor is a figure of speech where a word or phrase is applied and it’s not literal.
Example: it’s raining cats and dogs. It’s not really raining literal cats and dogs. It’s just raining really hard.

Most likely a is the answer - because  you generate   38 atp's but also consume an atp.   each atp gives approx. less than 4 kcal so probably a is the closest answer.
