a)

It speeds up

b)

It slows down

c)

It stops completely

d)

It stays the same

2.

A muscle cell has very low ATP levels and needs more energy. Which process will increase to produce ATP?

a)

Gluconeogenesis

b)

Glycolysis

c)

Fatty acid synthesis

d)

Glycogen storage

3.

During a workout, muscle contractions trigger glucose uptake without the need for insulin. Which glucose transporter is responsible for this process?

a)

GLUT 1

b)

GLUT 2

c)

GLUT 3

d)

GLUT 4

4.
