During cellular respiration, acetyl CoA accumulates in which location?

mitochondrial intermembrane space

Even though plants carry on photosynthesis, plant cells still use their mitochondria for oxidation of pyruvate. When and where will this occur?

in photosynthetic cells in the light, while photosynthesis occurs concurrently

in nonphotosynthesizing cells only

in cells that are storing glucose only

Which statement describes the functioning of photosystem II?

The electron vacancies in P680+ are filled by electrons derived from water.

Light energy excites electrons in the thylakoid membrane electron transport chain.

Photons are passed along to a reaction�center chlorophyll.

The P680 chlorophyll donates a pair of protons to NADP+, which is thus converted to NADPH.

Why are C4 plants able to photosynthesize with no apparent photorespiration?

They use PEP carboxylase to initially fix CO2.

They do not participate in the Calvin cycle.

They are adapted to cold, wet climates.

They conserve water more efficiently.

CAM plants keep stomata closed in daytime, thus reducing loss of water. They can do this because they

fix CO2 into organic acids during the night.

fix CO2 into sugars in the bundle�sheath cells.

fix CO2 into pyruvate in the mesophyll cells.

use photosystem I and photosystem II at night.

What is the function of NADP+?

It is a light-reflecting pigment

It acts as long-term energy storage

How is C 4 photosynthesis differ from C 3 photosynthesis?

C 4 plants are more efficient CO 2 fixers than are C 3 plants

C 4 plants require more water for photosynthesis than C 3 plants.

C 4 plants can photosynthesize better in lower levels of light than can C 3 plants.

In the C 4 plants , chlorophyll P 680 is more efficient than it is in C 3 plants.

All of the following are true about photosynthesis EXCEPT:

The Calvin cycle usually occurs in the dark

The majority of the light reaction occurs on the thylakoid membrane of the chloroplast

A proton gradient drives the formation of ATP from ADP+P i

How is a molecule reduced?

electrons are given to the molecule

money is taken from the molecule

protons are given to the molecule

Why must plants keep their stomata closed during hot days?

Open stomata release water, causing the plant to dry out.

Open stomata release too much CO 2 , starving the plants.

Open stomata cause the plant to lose access to CO 2 molecules

Open stomata lead to a buildup of O 2 molecules in the cells.

Why does sprinting lead to a burn in the muscles?

The lack of oxygen leads to lactic acid fermentation

The lack of oxygen leads to alcohol fermenation

The increased oxygen consumption speeds up cellular respiration, overheating the muscles

The decreased oxygen production overwhelms the signal proteins in your lungs

Where does Glycolysis take place?

Across the outer mitochondrial membrane

Across the inner mitochondrial membrane

What is produced through Glycolysis?

2 molecules of acetyl coenzyme-A

What is the purpose of fermentation?

To reset molecules for Glycolysis

To produce additional ATP in the absence of oxygen

To move Glycolysis into the aerobic portions of cellular respiration

During aerobic respiration, electrons travel downhill in which sequence?

food � NADH � electron transport chain � oxygen

food � citric acid cycle � ATP � NAD+

glucose � pyruvate � ATP � oxygen

glucose � ATP � electron transport chain � NADH

When electrons flow along the electron transport chains of mitochondria, which of the following changes occurs?

The pH of the matrix increases.

ATP synthase pumps protons by active transport.

The electrons gain free energy.

The cytochromes phosphorylate ADP to form ATP.

The accumulation of free oxygen in Earth's atmosphere began

with the origin of cyanobacteria that had both photosystem I and photosystem II.

with the origin of life and respiratory metabolism.

with the origin of photosynthetic bacteria that had photosystem I.

with the origin of chloroplasts in photosynthetic eukaryotic algae.

What is the purpose of splitting water in PS2 of the light dependent reaction?

Provides e- for PS2 and H+ for the thylakoid space

If the input water is labeled with a radioactive isotope of 18 O , then the oxygen gas released as the reaction proceeds is also labeled with 18 . Which of the following is most likely the explanation?

During the light reaction of photosynthesis , the water split, removing electrons and protons and oxygen is released in the atmosphere

During the light reaction of photosynthesis the water is split, the hydrogen atom combines with CO 2 and O 2 gas is released

During the Calvin cycle , water is split , regenerating NADPH from NADP + , and oxygen is released

During the Calvin cycle, water is split, the hydrogen atoms are added to immidiates of sugar synthesis, and oxygen gas is released.
