Exam 6: Photo Synthesis and Cellular Respiration

All of the following elements can be found in the photosynthetic intermediary molecules that lead to the production of sugar; which element does NOT remain in the final product?

The energetics of photosynthesis often overshadows the importance of carbon fixation; without the vital process of carbon fixation,what would happen?

The innermost membrane in a chloroplast is the ________ membrane.

During the Calvin cycle,the enzyme rubisco forms an unstable carbohydrate by combining CO₂ with a compound that contains ________ carbons.(Hint: The answer is a number.)

A fermentation pathway is an oxidative pathway in which the electrons that are released from a nutrient molecule are transferred to molecules created by the catabolism of the nutrient.In lactic acid fermentation,what molecule receives electrons?

When yeasts are exposed to anaerobic conditions,they regenerate NAD⁺ from NADH in a series of reactions that make CO₂ and ________.

The outcome of the Calvin cycle is the

The process that produces ATP from sugars begins with glycolysis; when fatty acids are used as nutrients to generate ATP instead of sugars,the process begins with

The burning pain we feel in our muscles during strenuous exercise is a result of

The muscle cells of a very active organism would contain fewer mitochondria than those of a less active organism.

Because inorganic carbon cannot be used by living organisms to build biological molecules,carbon fixation may be the most important metabolic process in the biosphere; if so,the most important enzyme in the biosphere would be

The enzyme rubisco is important to the process of

Today,the pathways of photosynthesis and cellular respiration are complementary and relatively balanced,but early in the history of life on Earth,photosynthesis appears to have dominated.One piece of evidence that suggests the early dominance of photosynthesis is the

A funnel is used to channel substances that are collected over a wide area into a narrow-necked container.In the Calvin cycle,a funnel might be a good analogy for the

What is the importance of photosynthesis to organisms other than plants?

The light reactions in photosynthesis result in three output products: molecular oxygen,ATP,and ________.

Alcohol is a by-product of fermentation by yeast.

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

Light consists of massless particles called photons,each of which travels through space with a wavelike oscillation.Photons that have more energy content have wavelengths that are ________.

The Krebs cycle takes place in the
