Exam 9: Photosynthesis and Cellular Respiration

Cells use a variety of metabolic pathways to construct ATP, but each concludes with the same step. Which of the following describes the final step by which ADP becomes ATP?

Acetyl CoA is a substrate of

The process that produces ATP from sugars begins with glycolysis; when fatty acids are used the process begins with

During exercise, the increase in respiration rate and heartbeat speed are driven by the need to replenish the oxygen used to support

Most Tibetans do not compensate for the low oxygen of their environment with an increase in red blood cells; perhaps their mitochondria have evolved a less oxygen-dependent method of catabolizing sugar and producing CO₂.

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

The conversion of inorganic carbon from air into the carbon atoms found in all living organisms is known as carbon ____________________.

Several energy carriers can be found in eukaryotic cells; the most versatile, as indicated in the illustration below, is

The outcome of the Calvin cycle is the

The NADH produced by the Krebs cycle donates electrons to the electron transport chain.

The mitochondria of plants contain thylakoids.

During the process of photosynthesis, plants capture the kinetic energy of moving photons and transform it into potential energy in the form of

During alcoholic fermentation, pyruvate is converted to ethanol in order to

Fermentation produces more ATP molecules than aerobic respiration does.

The green pigment most commonly associated with photosynthesis is ____________________.

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

The energy source that makes oxidative phosphorylation possible comes from

Alcohol is a by-product of fermentation by yeast.

Glycolysis occurs in the _____ of a cell.

The three stages of aerobic catabolism are
