topic c cell respiration

ATP THINGS

• ADP (adenosine diphosphate) + Pi (inorganic phosphate) when used

Reversible reactions through hydrolysis and condensation:

1. ATP + H₂O → ADP + phosphate + energy

cellular respiration

process of controlled released of energy from organic compound in cells

Main Substrates for Cell Respiration

glucose, fatty acids, and aminoa acids

steps of respiration

1. glycolisis cytoplasm (glucose breakdown into 2 pyruvate releasiing 2 atp (anaerobic in cytoplasm)

2. link reaction

3. krebs cycle

4. the oxidative phosphorylation all 3 in mitochondria

diff between aerobic and anaerobic

Feature	Aerobic respiration	Anaerobic respiration
Oxygen Requirement	Requires oxygen	Does not requires oxygen
Location	Mitochondria (Krebs cycle, electron transport chain)	Cytoplasm (Glycolysis and fermentation)
Substrate	Glucose, fatty acids, amino acids	Glucose
ATP Yield	High (36-38 ATP per glucose molecule)	Low (2 ATP per glucose molecule)
By-Products	Carbon dioxide and water	Lactic acid (humans) or ethanol and CO₂ (yeast)
