What happens to your enzymes when they get too hot? The enzymes denature and the active site alters, so the substrate can't fit in there properly and chemical reactions don't happen as fast.

The enzyme changes shape, but the substrate still fits in and the chemical reaction can still take place.

The enzyme dissolves and the pieces then need to be rebuilt before they can be used again.

Nothing, the enzyme can handle temperature changes in the body.

Agroup of plant cells was exposed to radiation, which damaged the chloroplasts and caused them to lose function. if the mitochondria were unharmed, what would happen to the overall function of the plant cells? a. the cells would not be able to make food, but would be able to release energy from biomolecules. b. the cells would not be able to replicate dna, but would be able to break down waste. c. the cells would not be able to break down waste, but would be able to replicate dna. d. the cells would not be able to release energy from biomolecules, but would be able to make food.
