The site of photosynthesis

Chloroplast

What are the 2 stages of photosynthesis?

Light-dependent reactions and Calvin Cycle (light-independent reactions)

What stage of photosynthesis is this?

• Sunlight is captured to make energy carriers

• Site: Thylakoids (in chloroplast)

• Reactants: Sunlight + Water

• Products: Oxygen, ATP, NADPH

Light-Dependent Reactions

Limiting Factors of Photosynthesis? (at least 3)

• Sunlight availability

• Temperature

• Carbon Dioxide

Cellular Respiration

The process where both plants and animals convert glucose produced during photosynthesis into CO2 and water, releasing energy in the form of a much larger, long-term supply of ATP

Used to power various energy-dependent processes within the cell

Adenosine triphosphate (ATP)

Primary location of cellular respiration?

Mitochondria
