Question

question 3 (1 point)
when does the process of incorporating the carbon of carbon dioxide into carbohydrates occurs
during the light reaction
during the calvin cycle
during the carbon fixation
both b and c
during phtorespiration
question 4 (1 point)
in the mitochondrial inner membrane infolding is called
cristae
stroma
o₂
matrix

Explanation:

• Question 3: The Calvin cycle is the process where carbon - fixation occurs, incorporating carbon from carbon dioxide into carbohydrates. Carbon - fixation is a part of the Calvin cycle. Photorespiration is a different process and light reactions are mainly for generating ATP and NADPH.
• Question 4: The infoldings of the mitochondrial inner membrane are called cristae. Stroma is in chloroplasts, O₂ is a gas, and matrix is the space inside the inner membrane but not the infolding.

Answer:

• Question 3: D. both B and C
• Question 4: A. Cristae
