18.Select the statement below that is false concerning aerobic cellular respiration O a Cells are able to utilize all the energy from glucose when released in one burst.

O b. Cells would lose too much energy as heat if they used glucose directly for individual reactions

O c. Gradual glucose breakdown releases energy slowly.

O d. Cells would lose too much energy as nonusable heat if they used glucose directly.

O e. Gradual glucose breakdown allows for the simultaneous buildup of many ATP molecules.

Animal bodies (and even plant bodies for that matter) are complex enough that life couldn't exist without enzymes. enzymes are usually large, complex biological catalysts that are expensive to make. enzymes speed up the rate of chemical reactions without being used up during the reaction (they can be reused many times). they are highly specific in the reactions they regulate. knowing what enzymes are and how they function, why does this explain why complex life forms could not exist if there were no enzymes.
