During the second half of glycolysis, what occurs?
atp is used up.
fructose is split in two.
atp is made.
glucose becomes fructose.

During the second half of glycolysis , ATP is made occurs .

Explanation:

Glycolysis -

In the first pathway of Glycolysis in the cytoplasm , it breakdowns the glucose to release energy .

Glycolysis has two parts -

In the first part , the six carbon moiety glucose break down to two three - carbon sugar moieties , in this process two molecule of ATP are invested .

In the second part , glycolysis extracts ATP and electron of high energy from the hydrogen atoms and gets attached to the NAD⁺ , in this process four ATP molecules are formed by the substrate phosphorylation .

Hence,

In the net process , Two molecules of ATP are formed .

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.
