Cell respiration

Cell respiration

Controlled release of energy from organic compounds to produce ATP

Role of ATP in CR

ATPis an immediate source of energy

How much ATP does anaerobic CR yield from glucose.

Small yield

What is required for aerobic CR and what does in yield?

Requires oxygen and gives a large yield of ATP from glucose

Anaerobic CR in yeast is used in baking because

It produces ethanol and carbon dioxide to help the dough rise

Main organic compounds in cr

Carbs, but lipids and proteins can also be digested

Anaerobic - what and where?

Partial breakdown of glucose in the cytosol

Aerobic - what and where?

Utilizes oxygen to completely breakdown glucose for a large ATP yield in the mitochondria

Complete equation

C6H12O6 + 6O2 = 6co2 +h2o +ATP

ATP and its structure

High energy molecule that functions as an immediate source of power for cell processes. It contains three covalently linked phosphate groups that store potential energy in their bonds

How does cr regenerate ATP?

Uses energy stored in organic molecules to regenerate ATP from ADP +Pi via oxidation

ATP AND ADP

ATP can be phosphoryllated from ADP

Lactate production-why?

To maximise the power of muscle contractions
