UofC BIOL211 Topic 5+6: Cellular Respiration and Photosynthesis

Where does photosynthesis occur

Chloroplasts

Where does cellular respiration begin

Cytosol

Where does aerobic cellular respiration mainly occur

Mitochondria

What is the energy source for photosynthesis

Light

What is the energy source for cellular respiration

Chemical energy stored in organic molecules

Aerobic respiration reactants

Glucose, oxygen

Aerobic respiration products

Carbon dioxide, water, ATP

Photosynthesis reactants

Carbon dioxide, water, light energy

Photosynthesis products

Oxygen, glucose

What does photosynthesis produce for cellular respiration

Organic molecules and oxygen

What does cellular respiration produce that photosynthesis uses

Carbon dioxide and water

What is the role of ATP in both processes

Provide usable cellular energy

What is the role of electron carriers in both processes

Transfer high

What is chemiosmosis in both processes

Proton flow through ATP synthase to produce ATP

Where is the proton gradient formed in mitochondria

Across the inner mitochondrial membrane

Where is the proton gradient formed in chloroplasts

Across the thylakoid membrane

What powers ATP production in mitochondria

Energy associated with electron transport and the proton gradient

What powers ATP production in chloroplasts

Light

What is the main difference between photosynthesis and cellular respiration

Photosynthesis stores energy in organic molecules; respiration releases energy from them
