organisms such as plants, which make their own food
organisms such as animals, that cannot use the sun's energy directly; obtain energy from the foods they consume
adenosine triphosphate (ATP)
one of the principal chemical compounds that cells use to store and release energy
plant use the energy of sunlight to convert water and carbon dioxide into high-energy carbohydrates-sugars and starches-and oxygen, a waste product
light-absorbing molecule plants gather
the plant's principal pigment
saclike photosynthetic membranes in chloroplasts
clusters where proteins in the thylakoid membrane organize chlorophyll and other pigments
the region outside the thylakoid membranes
carrier molecule that accepts and holds 2 high-energy electrons along with a hydrogen ion
reactions that require light
protein in cell membrane that spans the membrane and allow H+ ions to pass through it
when plants use the energy that ATP and NADPH contain to build high-energy compounds that can be stored for a long time
