Cellular Respiration and Photosynthesis

What is the primary function of the light reactions of photosynthesis?

• To produce glucose

• To use ATP

• To produce NADPH and ATP

• To produce RuBP

Glycolysis splits glucose into 2 molecules of

• Acetyl CoA

• Pyruvate

• Citric Acid

• Fructokinase

What is the function of NADP+?

• It absorbs light

• It is a light-reflecting pigment

• It acts as long-term energy storage

• It is an electron carrier

In the absence of oxygen, ____ follows glycolysis.

• pyruvate oxidation

• fermentation

• the citric acid cycle

• the calvin cycle

The light reactions occur in the ________ and the dark reactions take place in the ________.

• Chloroplast/thylakoid membrane

• Stroma/thylakoid

• mesophyl/stomata

• thylakoid membrane/stroma

The inner membrane of the mitochondria has an increased surface area due to numerous foldings. These foldings are called:

• cristae

• stroma

• matrix

• ER

When oxygen is released as a result of photosynthesis, it is a direct by-product of

• reducing NADP+

• chemiosmosis

• splitting water molecules

• electron transfer in photosystem II and I

The final electron acceptor in the electron transport system is _____. (In aerobic respiration)

• water

• oxygen

• NAD+

• FADH₂

The H+ concentration gradient is used to (in both respiration and photosynthesis)

• make NADPH

• generate ATP

• split water molecules

• make NADH

How many ATP molecules are produced when FADH2 delivers electrons to the electron transport system?

• 1

• 2

• 4

• 36
