Respiration Flashcards
ATP
Adenosine triphosphate, employed to do work in a cell
Three components of ATP
Adenine, ribose, triphosphate group
Exergonic process
One that breaks down materials, releasing energy
NADH
An electron carrier employed in photosynthesis
Redox reactions
A chemical reaction where electrons are transferred between chemicals
Glycolysis
Process of splitting sugar into two pyruvate molecules, which oxidize to acetyl CoA
Citric acid cycle
Breaks down the pyruvate to carbon dioxide, releasing energy through electron carriers
Oxidative phosphorylation
Produces over 90% of energy from cellular respiration
Glycolysis products (ATP, NADH, sugars)
2 ATP, 2 NADH, 2 pyruvates
Citric acid cycle products (one turn)
1 ATP, 3 NADH, 1 FADH2, 2 CO2
Electron transport chain
A collection of proteins within the mitochondrial membrane that pumps protons into the intermembrane space
ATP synthase
An enzyme that makes ATP from ADP harnessing the proton gradient
Chemiosmosis
Flow of protons across a membrane to drive cell work
Amount of ATP from cellular respiration
30 to 32
Number of ATP from one NADH
2.5
