Question

classify the given scenarios as endergonic or exergonic.
answer bank
a ball rolling down a hill
metabolizing proteins into amino acids
breaking down glucose in cellular respiration
constructing dna from nucleotides
pedaling a bike up a steep hill
generating carbohydrates in photosynthesis

Explanation:

Endergonic reactions require energy input, while exergonic reactions release energy. Constructing DNA from nucleotides and generating carbohydrates in photosynthesis need energy, so they are endergonic. Pedaling a bike up a steep hill also requires energy input. A ball rolling down a hill, metabolizing proteins into amino acids, and breaking down glucose in cellular respiration release energy and are exergonic.

Answer:

Endergonic: constructing DNA from nucleotides, pedaling a bike up a steep hill, generating carbohydrates in photosynthesis
Exergonic: a ball rolling down a hill, metabolizing proteins into amino acids, breaking down glucose in cellular respiration
