Openstax Biology 2E Chapter 8 Study Questions

P700 first transfers an electron through chlorophyll and a bound

P700 first transfers an electron through chlorophyll and a bound

quinone

Organic molecules are made in the

Calvin cycle.

What properties are expressed by wavelengths

1. Visible light's wavelengths are between 400-740nm

2. Red absorbs little energy

3. Chlorophyll b absorbs a lot of energy from 460nm wavelengths.

What is the flow of energy in order from source to end

sun→grass→cow→human

What statement shows the relationship among chloroplasts and mitochondria

both generate ATP by proton gradient

Light-dependent reactions build NADPH and oxygen by

oxidation and reduction

If rubisco does not function properly, what process would be affected

ability to fix carbon

Protons from electron transport will amass in the

thylakoid lumen

Why is the third stage of the Calvin cycle called the regeneration stage

Because Ribulose 1,5-bisphosphate (RuBP), the molecule needed at the start of the cycle, is regenerated from Glyceraldehyde 3-phosphate (G3P)

The light independent reactions are important because they

convert CO2 into glucose
