CAM

Which of the following is an example of osmosis?

Cells in our kidneys reabsorb water to reduce the amount of water lost in our urine.

What two things are added to NADP+ to convert it into NADPH?

H+ and electrons

The O2 given off during photosynthesis is derived from

H2O

Which of the following is a by-product of photosynthesis that is used during cellular respiration?

Why do leaves and vegetables with high concentrations of carotenoids appear yellow or orange?

The carotenoids reflect yellow and orange wavelengths of light.

Which of the following is an example of potential energy rather than kinetic energy?
