Metabolism

Metabolism

Sum of all chemical reactions in body

Anabolism

Building complex molecules from simpler ones (requires energy)

Catabolism

Breaking down complex molecules into simpler ones (releases energy)

Hydrolysis

Water molecule used to break down chemical bonds

Dehydration synthesis

Joining bonds by releasing a water molecule

C6H12O6+6O2>6CO2+6H20+ATP

Oxidation of glucose

Basal metabolic rate

Minimum energy your body needs at rest to maintain homeostasis

Direct calorimetry

Measuring metabolic rate by directly measuring heat produced by body

Indirect calorimetry

Measuring metabolic rate by measuring gas exchange

Surface area to volume ratio

Affects how efficiently exchange can occur between cells (larger cells have smaller sav, harder to obtain nutrients)

Glycolysis

Converting glucose to pyruvate acid (breaking sugar molecules into simpler molecules)

Formation of Acetyl CoA

Produced by breakdown of carbs and fats by pyruvate oxidation. Removes co2 and attaches coa to acetyl group

Krebs Cycle

Releasing energy from nutrients through acetyl coa oxidation. Energy released is ATP

Oxidative phosphorylation

Producing ATP through the electron transport chain, transferring electrons from NADH and FADH2

Substrate level phosphorylation

Phosphate group transferred from substrate group to ADP to make ATP

Respirometer

Measures rate of respiration (tidal and minute volume)
