Exam 9: Cellular Respiration and Fermentation

Approximately how many molecules of ATP are produced from the complete oxidation of two molecules of glucose (C₆H₁₂O)in aerobic cellular respiration?

In chemiosmotic phosphorylation,what is the most direct source of energy that is used to convert ADP +℗ ᵢ to ATP?

Use the following figure to answer the questions below. -What happens at the end of the chain in the figure above?

The figure below illustrates some of the steps (reactions)of glycolysis in their proper sequence.Each step is lettered.Use these letters to answer the questions. -Which portion of the pathway in the figure above contains a phosphorylation reaction in which ATP is the phosphate source?

An organism is discovered that thrives both in the presence and absence of oxygen in the air.Curiously,the consumption of sugar increases as oxygen is removed from the organism's environment,even though the organism does not gain much weight.This organism

Use the following information to answer the questions below. In the presence of oxygen,the three-carbon compound pyruvate can be catabolized in the citric acid cycle.First,however,the pyruvate (1)loses a carbon,which is given off as a molecule of CO₂,(2)is oxidized to form a two-carbon compound called acetate,and (3)is bonded to coenzyme A. -These three steps result in the formation of

During aerobic respiration,H₂O is formed.Where does the oxygen atom for the formation of the water come from?

What is the term for metabolic pathways that release stored energy by breaking down complex molecules?

Which of the following statements describes NAD⁺?

When skeletal muscle cells undergo anaerobic respiration,they become fatigued and painful.This is now known to be caused by

Why is glycolysis described as having an investment phase and a payoff phase?

The figure below illustrates some of the steps (reactions)of glycolysis in their proper sequence.Each step is lettered.Use these letters to answer the questions. -Which step in the figure above shows a split of one molecule into two smaller molecules?

Use the following information to answer the questions below. Exposing inner mitochondrial membranes to ultrasonic vibrations will disrupt the membranes.However,the fragments will reseal "inside out." These little vesicles that result can still transfer electrons from NADH to oxygen and synthesize ATP.If the membranes are agitated further,however,the ability to synthesize ATP is lost. -After the first disruption,when electron transfer and ATP synthesis still occur,what must be present?

What happens to the acetyl groups produced during beta-oxidation of fat?

The oxygen consumed during cellular respiration is involved directly in which process or event?

When a molecule of NAD⁺ (nicotinamide adenine dinucleotide) Gains a hydrogen atom (not a proton),the molecule becomes

Carbon dioxide (CO)is released during which of the following stages of cellular respiration?

Use the following information to answer the questions below. You have collected samples from mud at the bottom of a nearby pond and have isolated different bacteria and protists from that community.You put the cultures in appropriate media in test tubes with loose-fitting lids and leave for the night,confident that your cultures will be growing well when you return. -Test tube B has a strong smell of rotten eggs.This culture must contain

Use the following figure to answer the questions below. The citric acid cycle. -Which of the following is a likely reason that newborn infants have increased amounts of brown fat?

________ is the process whereby hydrogen is removed from sugars and fats and transferred to oxygen.
