Metabolism

Catabolism

Metabolic process that generates energy by breaking down large, complex materials into smaller molecules

Anabolism

A metabolic process that consumes energy through the synthesis of larger molecules from smaller molecules

Oxidation Reaction

Losing electrons

Reduction Reaction

Gaining electron

What goes in during glycolysis?

1 Glucose (6C), 2 ATP , 2 NAD+

What comes out during glycolysis?

2 NADH, 4 ATP, 2 Pyruvate (2 × 3C)

Enzyme Class: Kinases

Transfers a phosphate group from ATP to substrate

Enzyme Class: Isomerases

An enzyme that converts one isomer to another

Pyruvate

• made in the cytosol through glycolysis then transported to the mitochondria

• 3 carbon molecule

What goes in Pyruvate Breakdown

2 pyruvate (3 carbon)

What comes out of Pyruvate breakdown?

2 NADH, 2 CO2, 2 Acetyl Coa

Where does pyruvate breakdown occur in the cell

mitochondrial matrix

Where does glycolysis occur in the cell

Cytosol

Pyruvate travels from the cytosol to the inner membrane space via

passive diffusion

Pyruvate travels from the inner membrane space to the mitochondrial matrix via

Mitochondrial matrix complex embedded in the membrane

What goes into the Citric Acid Cycle

1 Acetyl-Coa, NAD+, FAD

Enzyme Class: dehydrogenase

Removes hydrogen from a molecule and transfer them to an electron acceptor

Reducing Agent

A molecule that donates an electron to another during a redox reaction, therefore oxidizing itself

respiration

The process in which cells turn food into energy

what comes out of the citric acid cycle

2 CO2, NADH+, 1 FADH2, , 1 ATP

What goes into oxidative phosphorylation

NADH, FADH2, O2

What goes out of oxidative phosphorylation

28 ATP, H2O

What goes into the calvin cycle

18 ATP, 12 NADPH

What goes out of the calvin cycle

2x 3 Carbon molecules
