Photosynthesis Check-In - Jenn Fitzgerald | Laabri

This should be completed individually after playing the Photosynthesis game. You may refer back to your notes if you need to.

Ɛhia

1

What part of the plant cell performs photosynthesis?

The chloroplast

The mitochondria

The nucleus

The cell wall

Ɛhia

What does light do when it strikes the chlorophyll molecules of photosystems I and II?

Light causes the conversion of water into carbon dioxide, oxygen and electrons

Light causes glucose to be synthesized directly inside the chlorophyll molecules of the photosystems

Light causes electrons to get excited (gain energy) and travel down an electron transport chain embedded in the thylakoid membrane

Light directly causes carbon dioxide to attach to RuBP during the carbon fixation stage of the Calvin cycle

Ɛhia

1

Which products of the light-dependent reactions are used in the Calvin cycle to help form organic compounds?

Water and Carbon dioxide

Light, Water, and Carbon dioxide

ATP & NADPH

Oxygen, ATP, NADPH, and Carbon dioxide

Ɛhia

1

What happens during the carbon fixation stage of the Calvin cycle (light-independent reactions)?

Oxygen is produced through this process

six carbon dioxide molecules combine with six 5-C compounds and make 12 molecules of 3-PGA

Energy from ATP and electrons from NADPH are used to reduce 3-phosphoglycerate (3-PGA) to form G3P molecules (which can be used to from organic molecules such as glucose)

The remaining G3P molecules that have not exited the cycle are used to re-form RuBP through a series of chemical reactions, so that the Calvin cycle can continue

What happens during step 2 of the Calvin Cycle now that we've made 3-PGA?

Oxygen is produced through this process

The remaining G3P molecules that have not exited the cycle are used to re-form RuBP through a series of chemical reactions, so that the Calvin cycle can continue

The enzyme Rubisco attaches Carbon dioxide to RuBP, causing the formation of a 3-phosphoglycerate (3-PGA)

Energy from ATP and NADPH are combined with the 3-PGA to form G3P molecules (which can be used to form organic molecules such as glucose)

What happens to the ten G3P molecules that remain in the Calvin Cycle?

Oxygen is produced through this process

The remaining G3P molecules that have not exited the cycle are used to re-form the 5-C molecule used to start the cycle through a series of chemical reactions, so that the Calvin cycle can continue

Energy from ATP and electrons from NADPH are used to reduce 3-phosphoglycerate (3-PGA) to form G3P molecules (which can be used to form organic molecules such as glucose)

The enzyme Rubisco attaches Carbon dioxide to RuBP, causing the formation of a 3-phosphoglycerate (3-PGA)
