Chapter 6 vocab Flashcards
any pigment in chlorophyll that assists in capturing light energy.
accessory pigment
a substance involved in energy metabolism formed by the breakdown of adenosine triphosphate.
adenosine diphosphate
an enzyme that catalyzes the synthesis of ATP from ADP and phosphates
ATP synthase
a series of chemical reactions in which the product of one reaction is consumed in the next reaction.
biochemical pathway
a light absorbing compound that functions as an accessory pigment in photosynthesis.
carotenoid
a process in chloroplasts and mitochondria in which the movement of proteins down their concentration gradients across a membrane is coupled to the synthesis of ATP.
chemiosmosis
a class of light absorbing pigments used in photosynthesis
chlorophyll
molecules in the thylakoid membrane or inner mitochondrial membrane that uses some of the energy in electrons to pump across the membrane
electron transport chain
a stack of thylakoids
granum
the initial reactions in photosynthesis
light reactions
nicotiminade adenine dinucleotide phosphate; organic molecule that accepts electrons during redox reactions
NADP +
the converting of light energy into chemical energy stored in organic compounds.
photosynthesis
unit of several hundred chlorophyll and carotenoid pigment molecules.
photosystem
second cluster of pigments where electrons are excited by light, involved in the light reactions
photosystem I
cluster of pigment molecules that begin the light reactions.
photosystem II
