Question

the venn diagram below shows the relationship between photosynthesis and aerobic cellular respiration.

1. match the numbered regions of the venn diagram above with the appropriate descriptions given below.

number:
description: carbon dioxide is fixed electron carrier molecules are oxidized glucose is broken down oxygen is produced
(record your four - digit answer in the numerical - response section on the answer sheet.)

1. choose the row that correctly describes the role of the etc in the mitochondria and the chloroplast.

row etc in the mitochondria etc in the chloroplast
a. oxidation of nadh and fadh₂ oxidation of glucose
b. photosystems embedded in the cristae membrane proteins embedded in the thylakoid membrane
c. production of atp through chemiosmosis reduction of nadp⁺
d. helps to produce oxygen psi receives electrons from psii

1. as electrons move from photosystem ii to the electron transport chain, they are replaced by electrons produced from

a. the entire electron transport system
c. carbon fixation
b. the splitting of water
d. chemiosmosis

Explanation:

Step1: Analyze photosynthesis - carbon dioxide fixation

Carbon - dioxide is fixed only in photosynthesis, so it corresponds to region 1.

Step2: Analyze electron - carrier oxidation

Electron - carrier molecules are oxidized in both photosynthesis and aerobic cellular respiration, so it corresponds to region 2.

Step3: Analyze glucose breakdown

Glucose is broken down only in aerobic cellular respiration, so it corresponds to region 3.

Step4: Analyze oxygen production

Oxygen is produced only in photosynthesis, so it corresponds to region 1.
The four - digit answer for question 13 is 1231.

For question 14:
In mitochondria, the electron - transport chain (ETC) is involved in the production of ATP through chemiosmosis by oxidizing NADH and FADH₂. In chloroplasts, the ETC is involved in the reduction of NADP⁺.

Answer:

1. 1231
2. C
3. B
