AP Biology Unit 3: Cellular Energetics Review

Front

Enzymes __________ activation energy to speed up chemical reactions.

Back

decrease

Front

Why is the hydrolysis of ATP important to a cell's function?

Back

It releases energy that can be used to power cellular processes.

Front

What are the products of the light reaction of photosynthesis?

Back

Oxygen, NADPH, ATP

Front

How does a plant obtain the carbon necessary to form glucose?

Back

Through CO2 absorbed from the atmosphere.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell.

Front

Define photosynthesis.

Back

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

Front

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, to drive the photosynthesis process.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What are the three main stages of cellular respiration?

Back

Glycolysis, Krebs cycle, and Electron Transport Chain.

Front

What is the significance of the Krebs cycle?

Back

The Krebs cycle generates electron carriers (NADH and FADH2) that are used in the electron transport chain to produce ATP.
