Medicinal Botany: Pollination Quiz

What is the overall equation for photosynthesis?

CO₂ + H₂O + Light → C₆H₁₂O₆ + O₂ (glucose)

What are the two main stages of photosynthesis?

Light dependent reactions and Light independent reactions (Calvin Cycle)

What are the starting materials for the light dependent reactions?

H₂O and Light

What are the products of the light dependent reactions?

ATP, NADH, and O₂ (as a byproduct)

Where do the light dependent reactions occur?

In the thylakoids of a chloroplast

What starts the light independent reactions (Calvin Cycle)?

CO₂, ATP, and NADH

What is the main product of the Calvin Cycle?

Glyceraldehyde 3-phosphate (G3P)

Where do the light independent reactions occur?

In the stroma of a chloroplast

What are the three fates of light when it hits a leaf?

Reflected, transmitted, and absorbed

What is chlorophyll fluorescence?

The re-emission of absorbed light at a different wavelength

What is the role of Rubisco in the Calvin Cycle?

It catalyzes the fixation of CO₂ to RuBP

What is produced during the reduction phase of the Calvin Cycle?

G3P (glyceraldehyde 3-phosphate)

What is the significance of ATP and NADPH in photosynthesis?

They are energy-producing molecules used in the Calvin Cycle

What is the byproduct of water splitting in the light dependent reactions?

O₂

What is the function of the electron transport chain (ETC) in photosynthesis?

To transfer electrons and produce ATP and NADPH

What is the role of thylakoid membranes in photosynthesis?

They house the components for the light dependent reactions

How many CO₂ molecules are fixed per turn of the Calvin Cycle?

1 CO₂ molecule
