honors biology 9- photosynthesis (unit 3, chapter 8)

adosine triphosphate (ATP)

one of the principal chemical compounds that living things use to store and release energy

heterotroph

a living thing that gets food by consuming, or eating, other living things

autotroph

a living thing that can capture energy from sunlight or chemicals to make its own food

photosynthesis

the process by which plants and other autotrophs use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches

thylakoid

a baglike photosynthetic membrane found in chloroplasts

stroma

the liquid-filled space surrounding the thylakoids in chloroplasts

NADP+

one of the molecules that accepts high-energy electrons from chlorophyll and carries them to other molecules during photosynthesis

light-dependent reaction

a reaction of photosynthesis that uses ATP, NADPH, and carbon dioxide to make high-energy sugars

light-independent reaction

a reaction of photosynthesis that uses light energy to make ATP and NADPH

photosystem

the light-collecting units of the chloroplast

electron transport chain

a series of proteins in which high-energy electrons are used to change ADP to ATP
