lqc 12c exam qs

Question 1

what stage of the carbon cycle involves a condensation reaction and fructose

Answer 1

glucose -> sucrose

Question 2

which stage of the carbon cycle involves the enzyme RUBISCO

Answer 2

CO2 -> GP

Question 3

describe the role of RUBISCO in the production of GALP in the light independant reaction

Answer 3

RUBISCO as an enzyme in the calvin cycle, involved in carbon fixation to form GP, GP converted to GALP using ATP and reduced NADP

Question 4

explain how the products of both the light dependant and light independent reactions are used to synthesise triglycerides

Answer 4

use of reduced NADP produced by light dependant reaction, use of ATP produced by light dependant reaction, this produces GALP used in synthesis of FAs. GALP converted to amino acids used to synthesise proteins
