What is the job of the mitochondria in cellular respiration?

To produce large amounts of ATP.

What is the process by which pigments are separated using a solvent and porous paper?

Chromatography

Pigments such as chlorophyll b, xanthophylls and Carotenoids help chlorophyll a capture light, they are called _____.

Accessory pigments.

What are the products of the light reaction?

ATP, NADPH2 and Oxygen.

Which wavelengths of light are most absorbed by chlorophyll molecules?

Reds and Blue/violets

What happens when water is split during the light reaction?

Oxygen is released, Hydrogen and electrons are picked up by NADP.

Which part of aerobic respiration produces the most amount of ATP?

ETC – electron transport chain

Which molecule has more energy ATP or ADP?

ATP

List the process that occur in aerobic respiration.

Glycolysis, Kreb Cycle and ETC/

How are the electrons used in the light reaction replaced?

By the splitting of water during the light reaction.

What are the name of the carrier molecules used in the Kreb Cycle?

NADH and FADH

How many total ATPs are produced in Glycolysis, Kreb Cycle and ETC respectfully?

2, 2 and 34 = 38 Total ATP for aerobic respiration.

What is the process by which certain bacteria living deep vent communities produce food from the sulfur coming from the vents in the earth’s crust?

chemosynthesis

Which is the final acceptor molecule for hydrogen at the end of the ETC?

Oxygen, which will make water when it bonds with hydrogen.

What process causes muscles to ache when they are over worked?

Lactic Acid Fermentation

What are the reactants of the Dark (Calvin) Reaction?

Carbon dioxide, ATP and NADPH2. Also RuDP is used in the Calvin Cycle.

The ultimate source of energy of almost all organisms living on earth is ______?

The sun.

What is the major product of the dark reaction?

Glucose

Where does the Calvin Cycle get it’s energy to fix carbon dioxide?

From the light reaction which produces ATP and NADPH2.

In what organelle does photosynthesis occur?

Chloroplast

What are the two final waste products produced in cellular respiration?

Carbon dioxide and water.

Why are photosynthesis and cellular respiration considered redox reactions?

Electrons are exchanged during various chemical reactions.

What type of organisms undergo photosynthesis?

Autotrophs

What type of organisms undergo cellular respiration?

Autotrophs and heterotrophs.

What determines whether an organism undergoes aerobic or anaerobic respiration?

The amount of oxygen available.

What are these structures?What occurs in them?

Grana The individual thylakoids are where the light reaction occurs.

Which of these occur in the light reaction, which occur in the Calvin (dark) cycle?ATP producedCarbon dioxide is “fixed”Light is needed.NADPH2 is made.NADPH2 is used.Glucose is made?

Light, dark, light, light, dark, dark.

The folds in the mitochondria are called:

cristae

During which process is carbon dioxide gas produced?

Kreb cycle.

What is another name for the Kreb Cycle?

The Citric Acid Cycle because citric acid is made in the first reaction.
