Starch is broken down into by the enzyme

Starch is broken down into glucose by the enzyme amylase.

Explanation:

Starch is a polymer, a long chain of subunits of the sugar glucose. They join together to form a macromolecule. As it is, starch is 'too big' to enter cells to be processed to obtain energy; it must be broken down into its glucose subunits first.

Amylase is an enzyme present in the human saliva, among other places, and is responsible for breaking starch down so it can be transported inside cells as glucose, and then turned into energy by the cellular respiration.

20. d.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
