The light reactions occur in the ________ and the Calvin Cycle takes place in the ________.

chloroplast / thylakoid membrane

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

electron transfer in photosystem II and I

What is the primary function of the Calvin cycle?

produce simple sugars from carbon dioxide

regenerate ATP for use in the light reactions of photosynthesis

produce carbon dioxide for use in the light reactions of photosynthesis

produce oxygen by oxidizing water

A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?

As the cells run out of oxygen they switch to anaerobic respiration (fermentation), which allows the cell to make small amounts of ATP in the absence of oxygen.

As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.

The cells will never run out of oxygen if the weightlifter is breathing.

As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP.

Which of the following statements are false?

Glycolysis occurs in the mitochondria

Glycolysis can occur with or without oxygen

Glycolysis is the first step in both anaerobic and aerobic respiration

Glycolysis produces 2 ATP, 2 Pyruvates, and 2 NADH

What is the correct equation for cellular respiration?

6O 2 + C 6 H 12 O 6 -> 6CO 2 + 6H 2 O + Energy

6O 2 + C 6 H 12 O 6 + Energy -> 6CO 2 + 6H 2 O

6CO 2 + 6H 2 O -> 6O 2 + C 6 H 12 O 6 + Energy

6CO 2 + 6H 2 O + Energy -> 6O 2 + C 6 H 12 O 6

Rubisco is important in which step of photosynthesis

carbon fixation when CO2 is connected to RUBP during calvin cycle

energizing the electrons in chlorophyll

regeneration phase as RUBP is made during calvin cycle

reduction of the carbon chain during the calvin cycle

What is one function of the other pigments besides chlorophyll, in the chloroplast?

to absorb different wavelengths than the chloroplasts

to block damaging wavelengths of light

to provide different colors to the leaves

to transfer energy to a separate photosystem beside the one using chlorophyll a and b.

What is the main job of the electron carriers in cellular respiration?

Transport electrons and hydrogen atoms to the electron transport chain

Capture energy throughout the process of cellular respiration

Provide the reactants for the process of cellular respiration

Pump positive hydrogen ions and shuttle electrons across the electron transport chain and contribute to chemiosmosis

The point of the Krebs Cycle is to...

Break down pyruvate to produce electron carrier molecules, FADH 2 and NADH, as well as CO 2 and ATP as byproducts

Produce high amounts of ATP using a proton gradient

Move high energy electrons through series of proteins to eventually bind with O 2 , creating water and protons

Use ATP and NADPH to produce 6 carbon sugars

Chemiosmosis is best described as...

The use of a proton gradient to power ATP Synthase and produce ATP

Moving high energy electrons through carrier molecules toward oxygen

The breakdown of pyruvate into electron carrier molecules

The enzyme that combines ADP and inorganic phosphate to produce ATP
