Cellular Respiration

Terms in this set (57)

cellular respiration
the process in which cells make ATP by breaking down organic compounds
photosynthesis
the process in which autotrophs convert light energy into chemical energy
which types of organisms undergo cellular respiration
both autotrophs and heterotrophs
what happens when organic compounds are broken down into simpler compounds
energy is released
what is the energy released by the organic compound mostly used to do
produce ATP
the products of cellular respiration (3)
CO2, water, and ATP
two stages of cellular respiration
glycolysis and aerobic respiration
glycolysis
a biochemical pathway in which one six-carbon molecule of glucose is oxidized to produce two three-carbon molecules of pyruvic acid
how photosynthesis and cellular respiration depend on each other
the products of photosynthesis are the reactants of cellular respiration, and the reactants of photosynthesis are the products of cellular respiration
anaerobic
does not require the presence of oxygen
aerobic respiration
pyruvic acid is broken down and NADH is used to make lots of ATP
what pyruvic acid undergoes with no oxygen present
fermentation
fermentation
the breakdown of pyruvic acid by enzymes, bacteria, yeasts, or mold in the absence of oxygen
type of reaction in cellular respiration
redox
redox reaction
one reactant loses electrons and another gains electrons
