AP Biology: Unit 3 Review (CED)

Front

What are the main electron carriers in the electron transport chain during cellular respiration?

Back

NADH and FADH2 are the main electron carriers in the electron transport chain.

Front

Where does the substrate bind on an enzyme?

Back

The substrate binds at the active site of the enzyme.

Front

In which part of the chloroplast does the Calvin cycle occur?

Back

The Calvin cycle takes place in the stroma of the chloroplast.

Front

What must happen to maintain order in cellular processes?

Back

Energy input must exceed energy loss to maintain order in cellular processes.

Front

Where does the electron transport chain occur?

Back

The electron transport chain occurs in the mitochondria and prokaryotic plasma membrane, as well as in chloroplasts.

Front

What is the role of NADH in cellular respiration?

Back

NADH acts as an electron carrier, transporting electrons to the electron transport chain.

Front

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

Back

The active site is where the substrate binds and the reaction occurs.

Front

What is the significance of the stroma in photosynthesis?

Back

The stroma is where the Calvin cycle takes place, synthesizing glucose from carbon dioxide.

Front

How does energy input relate to cellular processes?

Back

For cellular processes to function effectively, energy input must be greater than energy loss.

Front

What are the components of the electron transport chain?

Back

The electron transport chain consists of a series of protein complexes and other molecules that transfer electrons.
