• thylakoid

• inner membrane of the mitocohndria

Where does the Electron Transport Chain occur?

• cytoplasm

• mitochondrial matrix

• thylakoid

• inner membrane of the mitocohndria

Where does the light-dependent reactions occur?

• cytoplasm

• mitochondrial matrix

• thylakoid of chloroplast

• stroma of cholorplast

Where does the light-independent reactions occur?

Glucose is made from ​ (a)   .

• carbon dioxide
• oxygen
• light energy

During glycolysis,

• glucose is split into 2 pyruvic acids

• pyruvic acid is converted to carbon dioxide

• NADH and FADH2 delivers energized electrons and ATP is generated

During Krebs Cycle,

• glucose is split into 2 pyruvic acids

• pyruvic acid is converted to carbon dioxide

• NADH and FADH2 delivers energized electrons and ATP is generated

During oxidative phosphorylation,

• glucose is split into 2 pyruvic acids

• pyruvic acid is converted to carbon dioxide

• NADH and FADH2 delivers energized electrons and ATP is generated
