Biology Chapter 7

Phase of cellular respiration

Metabolic process by which larger molecules are synthesized from smaller ones; anabolic metabolism

Metabolic process that breaks down large molecules into smaller ones; catabolic metabolism

Metabolic reactions that use the energy primarily from carbohydrate but also fatty acid or amino acid breakdown to produce ATP molecules.

Ability of certain membranes to use a hydrogen ion gradient to drive ATP formation.

Cycilcal metabolic pathway found in the matrix of mitochondria that participates in cellular respiration; breaks down acetyl groups to carbon dioxide and hydrogen.

Short, fingerlike projections formed by the folding of the inner membrane of mitochondria.

Any of several iron-containing protein molecules that serves as electron carries in photosynthesis and cellular respiration.

Removal of amino group (-NH2) from an amino acid or other organic compound.

Chain of electron carriers in the cristae of mitochondria and thylakoid membrane of chloroplasts. As the electrons pass from one carrier to the next, energy is released and used to establish a hydrogen ion gradient. This gradient is associated with the production of ATP molecules.

Coenzyme of oxidation-reduction that becomes FADH2 as oxidation of substrates occurs and then delivers electrons to the electron transport system in mitochondria during cellular respiration.

Anaerobic breakdown of glucose that results in a gain of two ATP and end products such as alcohol and lactate.

Significant metabolite in both the glycoltic pathway and the Calvin cycle; G3P is oxidized during glycolysis and reduced during the calvin cycle.

Anaerobic meabolic pathway found in the cytoplasm that participates in cellular respiration and fermentation; it coverts glucose to two molecules of pyruvate.

The space between the outer and inner membrane of a mitochondrion.
