surface area

Question 23

Explain Redox Reactions

Answer 23

chemical reactions where one substance is oxidized ( loses an electron) and the other is reduced (gains electrons)

X

Question 25

C6H12O6 is the formula for -

Answer 25

Question 26

After the Citric Acid Cycle, glucose becomes

_ NADPH
_ FADH2
_ GTP
_ CO2

Answer 26

6
4
4
2

Question 27

Photorespiration is the process that wastes energy and reduces sugar production in plants by using _ instead of _

Answer 27

Oxygen instead of CO2

Question 28

When does photorespiration occur?

Answer 28

When Rubisco binds to oxygen by mistake under hot and dry conditions

Question 29

Main steps of Calvin Cycle are: (in order)

Answer 29

Carbon Fixation (1)

Reduction (2)

Regeneration (3)

Question 30

What occurs in Carbon - Fixation?

Answer 30

Co2 will join to RuBP, a 5- carbon molecule, through an enzyme known as Rubisco. They will form a 6-carbon molecule that will be broken down into two 3 carbon molecules known as 3PG

Question 31

what occurs during Reduction?

Answer 31

The two 3PG molecules from Carbon Fixation are phosphorylated; they receive a phosphate from the ATP made in light reactions.

Question 32

What occurs in Regeneration?

Answer 32

Most of the G3P formed in Reduction will be turned back into RuBP with the help of ATP

Question 33

In reduction, each molecule of 3PG is reduced into _

Answer 33

G3P
