What is required for aerobic respiration?

Oxygen

100

What is a photon?

An excited electron that is in a higher energy level than it's natural state

100

Where do the light reactions take place?

Thylakoid membrane

100

What is the goal of the Calvin Cycle?

To make carbohydrates

100

What does photorespiration produce?

CO2

200

Where does the majority of cell respiration take place?

Mitochondria
200

What is the thylakoid membrane?

The disk shaped structure containing chlorophyll

200

Why is light important for the light reactions?

Light energy excites the electrons to make them charged particles

200

What are the reactants of the Calvin cycle?

CO2, ATP, NADPH

200

When does photorespiration happen?

When COlevels are low and O2 levels are high

300

What are the "electron taxis" for cell respiration?

NADH and FADH2

300

What is the name of a stack of thylakoid membranes?

Granum

300

What are the electrons gained from the splitting of water used for?

Replacing the electron lost from PS2

300

Where does the Calvin Cycle Take place?

The stroma

300

What percentage of plants are C3 plants?

90%

400

How much net ATP does glycolysis produce?

2 (4-2)

400

What are the stomata?

Holes on the underside of the leaf that are the sites of gas exchange

400

How does ATP synthase get the energy to produce ATP?

From the H+ gradient of the thylakoid membrane

400

What are the 3 stages of the Calvin Cycle?

Carbon fixation, sugar production, regeneration of RuBP

400

How do C4 Plants avoid photorespiration?

Having an additional step and doing carbon fixation before the Calvin Cycle

500

How much ATP is created after 1 full round of cell respiration?

38 in theory, 30 in practice

500

Name one pigment molecule plants have other than chlorophyll

Which part of the Light Reactions forms NADPH?

PS 1

500

What is the key enzyme that is involved in the Calvin Cycle?

Rubisco

500

How do CAM plants avoid photorespiration?

Fixing carbon at night and only doing the Calvin cycle during the day
