AP Biology Unit 3 Review Flashcardizz

Front

What is chemiosmosis?

Back

The diffusion of protons down their concentration gradient.

Front

Where did photosynthesis first evolve?

Back

In prokaryotic organisms.

Front

How are the ATP synthase enzymes in photosynthesis and cellular respiration similar?

Back

They both rely on chemiosmosis of hydrogens down a gradient to power phosphorylation.

Front

What factors affect the rate of photosynthesis?

Back

CO2 concentration, H2O availability, Temperature, Light intensity.

Front

Where on an enzyme does the substrate bind?

Back

At the active site.

Front

Define photosynthesis.

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, to convert it into chemical energy.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the function of the electron transport chain?

Back

To transfer electrons through a series of proteins, creating a proton gradient that drives ATP synthesis.

Front

What is the significance of the active site on an enzyme?

Back

It is the region where substrate molecules bind and undergo a chemical reaction.
