MAJOR FEATURES OF GLYCOLYSIS, KREBS CYCLE, ELECTRON TRANSPORT SYSTEM, AND CHEMIOSMOSIS General Biology 1 Quarter 2 / Week 6

Glycolysis

first step in the breakdown of glucose to extract energy for cellular metabolism.

Also referred to as Embden-Meyerhof-Parnas or EMP pathway.

Krebs cycle

occurs in the mitochondrial matrix and

generates a pool of chemical energy (ATP, NADH, and FADH2) from

the oxidation of pyruvate, the end product of glycolysis.

citric acid cycle

also known as the Krebs cycle or the

tricarboxylic acid cycle

Pyruvate

transported into the mitochondria and loses carbon dioxide to form acetyl-CoA, a 2-carbon molecule.

oxidative phosphorylation

our major source of ATP and energy

electron transport chain

ast component of aerobic

respiration and is the only part of glucose metabolism that uses

atmospheric oxygen.

electron transport

chain.

accessory electron carriers

Chemiosmosis

used to generate 90% of the ATP made during

aerobic glucose catabolism

oxidative

phosphorylation

production of ATP

using the process of chemiosmosis in mitochondria

Adenosine triphosphate (ATP)

energy currency for cellular

processes.
