a. More energy is released by the original reaction.
b. Less energy is needed to start reaction B.
c. The original reaction is catalyzed.
d. Reaction B occurs at a slower rate.

Graph attached

b. Less energy is needed to start reaction B.

Explanation:

The graph shows two different reactions and the energy required over time

a. More energy is released by the original reaction.  - this is false, more energy is required for the original reaction to proceed

b. Less energy is needed to start reaction B.  - this is true, the peak of the curve is lower showing less energy is required

c. The original reaction is catalyzed.  - this is false, likely reaction B is catalyzed

d. Reaction B occurs at a slower rate.- false, they occur at the same rate.

the peripheral nervous system or pns contains the nerves, which leave the brain and the spinal cord and travel to certain areas of the body. the peripheral nervous system's main job is to send information gathered by the body's sensory receptors to the cns as quickly as possible.
