Cellular Metabolism

Front

Cellular Metabolism (respiration)

Back

total chemical changes that

occur inside a cell.

Front

ATP (adenosine triphosphate)—

Back

the most common and available

form of energy

Front

Two different types of metabolism:

1. Anabolism

Back

energy requiring process that builds larger

molecules from combining small molecules

Front

Two different types of metabolism:

2. Catabolism

Back

energy releasing process that breaks down large

molecules in to smaller ones.

Front

Cellular Respiration Equation:

Back

C6H12O6 + 6O2 6CO2 + 6H20 + energy (ATP)

Front

Aerobic

Back

requires O2

Front

The most common substance that is decomposed aerobically

is glucose

Back

The breakdown of glucose (C6H1206) into CO2 + H20 is a

continuous process.

Front

Three steps to cellular metabolism:

Back

1. Glycolysis—anaerobic respiration

** Does NOT require O2 **Occurs in the cytoplasm

2. Kreb’s Citric Acid Cyle—aerobic respiration ** requires O2

** occurs in the cristae of the mitochondria

3. Electron Transport (Transfer) system—aerobic ** requires O2

** occurs in the cristae of the mitochondria

Front

Phosphorylation

Back

adding a phosphate (PO4) .

Front

**oxidation

Back

loses electrons
