Which statement about ATP is correct?

a)

The molecule ADP contains stored energy. When the phosphate molecule is removed the energy is released.

b)

The molecule ADP contains stored energy. When the phosphate molecule is removed the energy is stored.

The product of CR is CO2 which photosynthesis will use.

b)

The product of CR is CO2 which Cellular Respiration will use.

c)

The product of photosynthesis CO2 will be used by CR.

d)

The product of photosythesis CO2 will be used by photosynthesis.

9.

When placing dialysis tubing in a beaker with a high concentration of toxins will the toxins go inside the bag or out of the bag and why?

a)

The toxins will move into the bag because of diffusion. Moving from high to low.

b)

The toxins will move out of the bag because of active transport

c)

The solutions will remain the same because the solution is isotonic

d)

The toxins will move into the bag because of osmosis. The water is moving from high to low.
