Biosynthesis

Question 1

Carboxylation Phase in calvin cycle

Answer 1

Ribulose 1,5-bisphosphate carboxylase catalyzes the addition of CO2 to ribulose 1,5-bisphosphate

Question 2

Reduction phase

Answer 2

PGA is converted to glyceraldehyde 3-phosphate by ATP and NADPH dehydrogenation

Question 3

Regeneration Phase

Answer 3

Regenerates RuBP

Question 4

Structures where CO2 is fix within

Answer 4

Carboxysomes

Question 5

Why does microcompartenization occur

Answer 5

To increase efficiency and/or sequester reactive metabolites

Question 6

Alternative pathways for CO2 fixation

Answer 6

Many reactions in TCA cycle are reversible. CO2 is a common product of the cycle and the reaction can run in reverse to add carbon

Question 7

Gluconeogenesis

Answer 7
