PHOTOSYNTHESIS AND RESPIRATION QUIZ

What do coenzyme A, CO2, oxaloacetate, and FADH2 all have in common?

They are all components or products of the citric acid cycle

They are part of the dark reactions of photosynthesis

They are part of the reactions of lactic acid fermentation

They are all elements of oxidative phosphorylation

TRUE ANSWER : ?
YOUR ANSWER : ?

A eukaryotic cell that can carry out only fermentation instead of the complete aerobic respiration of glucose

has mitochondria present

is lacking in O2

produces less CO2

all of these

TRUE ANSWER : ?
YOUR ANSWER : ?

NADP+ is reduced to NADPH during

calvin cylcle

none of these

light dependent reactions

photorespiration

TRUE ANSWER : ?
YOUR ANSWER : ?

Assume the combined processes of photosynthesis and cellular respiration, the electrons that start as part of H2O at the beginning of the light reactions end up attaching to

pyruvate to make ethanol

NADPH to make new glucose

electron transport carriers to make O2

O2 to make new H2O

TRUE ANSWER : ?
YOUR ANSWER : ?

The rate of photorespiration in most plants increases at.higher temperatures. Some plants have evolved a somewhat round-about system to deal with this problem. This series of reactions is called

C4 pathway

ETS (electron transfer system in light reactions

Photosystem II

Calvin cycle

TRUE ANSWER : ?
YOUR ANSWER : ?

Hydrogen (electron) acceptor in the light reactions is

FADH

NADP+

NAD+

ADP

TRUE ANSWER : ?
YOUR ANSWER : ?

Which of the following represents a correct ordering of the events that occur during the respiration of glucose in the absence of O2?

Glycolysis; citric acid cycle; oxidative phosphorylation

Oxidative phosphorylation; citric acid cycle; glycolysis

Glycolysis; oxidative phosphorylation; citric acid cycle

Glycolysis; fermentation

TRUE ANSWER : ?
YOUR ANSWER : ?

The cytochrome c oxidase complex

accepts electrons from cyt c

pumps protons out of the matrix space

all of these

donates four electrons to O2

TRUE ANSWER : ?
YOUR ANSWER : ?

The breakdown of glucose occurs by the process known as

fermentation

glycolysis

Krebs cycle

anaerobic respiration

TRUE ANSWER : ?
YOUR ANSWER : ?

Oxidative phosphorylation is to respiration as __________ is to photosynthesis

electron transport chain
