BIOL 133 WEEK 5 CHAPTER 8 | COMPREHENSIVE BIOLOGY STUDY GUIDE,
PRACTICE QUESTIONS & ANSWERS 2026/2027
The light independent reactions are important because they - correct answer ✔✔convert CO2 into
glucose
What properties are expressed by wavelength? - correct answer ✔✔- Chlorophyll b absorbs a lot of
energy from 460nm wavelength
- Visible lights wavelength are between 400-740nm wavelength
What is the flow of energy in order from source to end? - correct answer ✔✔sun->grass->cow->human
What statement shows the relationship among chloroplasts and mitochondria? - correct answer
✔✔both generate ATP by proton gradient
Light dependent reactions build NADPH and oxygen by - correct answer ✔✔oxidation and reduction
Organic molecules are made in the - correct answer ✔✔Calvin cycle
p700 first transfers an electron through chlorophyll and a bound - correct answer ✔✔quinone
If rubisco does not function properly, what process would be affected?
A. ability to split water
B. ability to absorb photons
C. ability to reduce NADP+
D. ability to fix carbon - correct answer ✔✔D. ability to fix carbon
Protons from electron transport will amass in the
A. stroma
B. intermembrane space
C. matrix
D. thylakoid lumen - correct answer ✔✔D. thylakoid lumen
Why is the third stage of the Calvin cycle called the regeneration stage? - correct answer ✔✔Because
ribulose 1,5-bisphosphate, the molecule needed at the start of the cycle, is regenerated from
Glyceraldehyde 3-phosphate
