Exam 8: Photosynthesis and Cellular Respiration

In mitochondria, ATP is produced in conjunction with proteins in the membrane that surrounds a region in the mitochondrion known as the ____________.

The inner membrane of a mitochondrion is highly folded. Which of the following explains why this is the case?

NAD⁺ becomes NADH when it gains two high-energy _____ and one proton.

Humans' large brains require a significant share of the body's production of _______, the most commonly used energy carrier.

It's OK to say that your brain is solar powered, because

Cellular respiration is, essentially, the opposite of photosynthesis.

The muscles of a very active organism would contain fewer mitochondria than the muscles of a less active organism.

A funnel is used to channel substances collected over a wide area into a narrow necked container. A funnel might be a good analogy for the

Which of the following elements does not become incorporated into the sugars produced by photosynthesis?

The Krebs cycle takes place in

Energy is used to force protons from the thylakoid space back into the stroma.

Most of the oxidation reactions that produce NADH in a cell take place in

During photosynthesis, the Calvin cycle

An electron transport chain is made up of a group of electron-accepting _______ embedded in a membrane.

Which of the following best describes the process by which ADP becomes ATP?

This is a diagram of the Calvin cycle, which is a series of enzymatic reactions that manufacture sugars. How many times must this cycle "turn" to make one molecule of glucose (six carbons)?

_______ reactions break down and gradually oxidize food molecules to produce energy.

The green pigment most commonly associated with photosynthesis is _______.

You have been shrunk to molecular size and find yourself in a chamber in a chloroplast where protons are being pumped into another chamber. You are in the ___________.

The number and arrangement of membranes within a chloroplast are important to the chloroplast's functions. How would the absence of these membranes affect the manufacture of ATP within a chloroplast?
