Question 1:

For example, an ice hockey player who engages in repeated bouts of high intensity, fast skating maneuvers will need (a) short bursts / (b) a sustained source of ATP. As a result, ice hockey players will typically use ANSWER CHOICES: (a) aerobic or (b) anaerobic respiration during a game.

Question 2:

It might also be the case that this ice hockey player will take creatine supplements to boost his performance. Why might this be so? 

ANSWER CHOICES: Choose all that may apply.

(a) Creatine increases the speed with which neural signals reach the muscle.

(b) Creatine in the blood allows the body to absorb more oxygen, which helps to fuel ATP production in the muscle cells.

(c) Eating more creatine leads to more creatine phosphate stores in muscles, which then equates to larger energy stores available for short, explosive bouts of energy use.

(d) Unlike oxidative phosphorylation, ATP can be formed within a fraction of a second from creatine phosphate sources, since only one enzymatic reaction is involved in this energy transfer.
