Quarter 2 ExamPractice Questions

Respiration

Name anaerobic respiration with yeast that produces Ethyl alcohol.

Alcoholic fermentation

The Energy of glucose is transformed to this.

ATP

NADPH and FADPH

Protein molecules that carry electrons

The step of respiration where 24 electrons are released and picked up by NADP and FADPH?

The Kreb’s Cycle

List what is inside of a respirometer.

*Cotton with KOH *nonabsorbant cotton

*organism being tested

Which animal would be affected most by temperature

changes?

Mouse, turtle, human, dolphin

Turtle

An acetyl group is formed in which step of

respiration?

Pyruvate Oxidation

What is incorrect in the reaction of respiration

below?

C6H12O6 + 6CO2 6H2O + 6O2 + 34 ATP

C6H12O6 + 6 O2 6H2O + 6CO2 + 36 ATP

What is “A” and “B” in the diagram?

A

B

A= MatrixB= Cristae

Compare the amount of ATP formed from one glucose molecule during aerobic and anaerobic respiration.

Aerobic respiration= 36 ATP

Anaerobic= 2 ATP

How is ATP formed from Chemiosmosis?

H+ ions are pumped across the

cristae membrane forming a gradient.

The H+ them diffuse back into the

cristae through ATP Synthase

proteins….where ADP is phosphorylized making ATP.

What products of respiration

are needed for photosynthesis?

Carbon dioxide and water.

What is a product of anaerobic respiration in muscle cells?

Lactic Acid

Photosynthesis

Type of plants, like desert plants close stomates during the

day to conserve water.

CAM Plants

Accessary pigments found in all green plants.

Carotenoids

When is carbon dioxide utilized in the

process of photosynthesis?

In the Dark reaction in the Calvin Cycle

Where does the energy come from in order to drive the C3

Cycle?

A little ATP from the Light

Reaction

Most of the ATP from Respiration

p680 and p700(photocenters)

Why is C3 photosynthesis called Carbon fixation? What

is the source of the carbon?

It is called carbon fixation because carbon is taken in as CO2 and used to make organic

molecules.

Chlorophyll a absorbs light of what

color and wavelength?

Color= red at 625-650 nm

Color= blue at 425-450 nm

What is the name for light energy?

Photons

What affects separation of pigments during chromatography?

Solvent used, medium used, capillary action and amount of pigment used

Why was DPIP used in the lab of rate of photosynthesis?

DPIP replaced NADPH in the reaction and is reduced (becomes more colorless) as photosynthesis occurs.

What is labeled as “A” and “B” in the diagram?

A B

C

A= Grana

B=Stroma
