C1.3 Photosynthesis

Question 1

Limiting factors of photosynthesis

Answer 1

Temperature, light intensity, carbon dioxide concentration

Question 2

Photosystem I

Answer 2

Reduces NADP+ → Creates NADPH - used in Calvin cycle.

Question 3

Photosystem II

Answer 3

Splits water → Produces O₂ + creates ATP.

Question 4

Thylakoid

Answer 4

Sac-like vesicle, appearing flattened arranged in stacks within chloroplasts. Contain photosystems.

Question 5

Rubisco

Answer 5

Rubisco is an enzyme that catalyzes the first step of the Calvin cycle (producing glucose) in photosynthesis.

Question 6

Stroma

Answer 6

Liquid surrounding thylakoid

Question 7

The Calvin cycle (light-independent)

Answer 7

Produces carbohydrates utilizing NADPH, ATP, and Rubisco

Question 8

Triose phosphate

Answer 8

Used to regenerate RuBP in the Calvin cycle

Question 9

Photolysis

Answer 9

Process in which photons break down inorganic chemicals, generating electrons for use in the light-dependent reactions
