Biology Semester 1 Test Review

Front

Stacks of small membrane-bound discs are called:

Back

Grana

Front

A(n) _______ is the basic unit of life.

Back

Cell

Front

Which process of cellular respiration generates the most ATP?

Back

Electron Transport Chain

Front

The main pigment responsible for photosynthesis is:

Back

Chlorophyll

Front

The energy a cell needs to build molecules or power cell respiration is supplied by:

Back

ATP

Front

What is the function of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the sun, to convert carbon dioxide and water into glucose and oxygen.

Front

Define cellular respiration.

Back

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

Front

What are thylakoids?

Back

Thylakoids are membrane-bound compartments inside chloroplasts that contain chlorophyll and are the site of the light-dependent reactions of photosynthesis.

Front

What is the role of the Krebs Cycle in cellular respiration?

Back

The Krebs Cycle, also known as the citric acid cycle, processes acetyl-CoA to produce electron carriers (NADH and FADH2) for the electron transport chain.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes.
