A drug is tested in the laboratory and also is found to develop holes in both mitochondrial membranes. Scientists suspect that the drug will be harmful to humale cells because it will inhibita. glycolysis.b. the citric acid cycle.c. the citric acid cycle and also oxidative phosphorylation.d. oxidative phosphorylation.


Which of the following statements concerning the chemical grooming of pyruvate is false?a. Each pyruvate loses a carbon atom, which is released as CO2.b. Two pyruvate molecules together contain less chemical energy than was uncovered in the original glucose molecule.c. Each pyruvate molecule has a CO2 added and also then joins via an NADH.d. Two molecules of pyruvate are each converted into two-carbon molecules joined to a coenzyme A molecule.


The finish products of the citric acid cycle incorporate every one of the complying with excepta. ATP.b. CO2.c. FADH2.d. pyruvate.


At the finish of the citric acid cycle, many of the energy staying from the original glucose is stored in ? a. ATP.b. NADH.c. CO2.d. pyruvate.


The mitochondrial cristae are an adaptation thata. rises the area for even more duplicates of the electron transport chain and ATP synthase complexes.b. carefully encloses the DNA hosupplied within the mitochondrial matrix.c. helps mitochondria divide in the time of times of biggest cellular respiration.d. permits the expansion of mitochondria as oxygen accumulates in the mitochondrial matrix.


As a scientist employed by the FDA, you"ve been asked to sit on a panel to evaluate a pharmaceutical company"s application for approval of a new weight loss drug referred to as Fat Ameans. The firm has actually submitted a report summarizing the results of their animal and also humale trial and error. In the report, it was noted that Fat Ameans functions by affecting the electron transfer chain. It decreases the synthesis of ATP by making the mitochondrial membrane permeable to H+, which permits H+ to leak from the intermembrane space to the mitochondrial matrix. This impact leads to weight loss.Fat Ameans prevents ATP from being made bya. avoiding the convariation of NADH to NAD+.b. ruining the H+ gradient that allows ATP synthase to job-related.c. avoiding glycolysis from emerging.d. slowing dvery own the citric acid cycle.


By-assets of cellular respiration includea. carbon dioxide and water.b. NADH and also ATP.c. FADH2 and NADH.d. oxygen and also warmth.


Which of the adhering to statements around the power yield of aerobic respiration is false?a. Less than 50% of the chemical power easily accessible in glucose is converted to ATP energy.b. Most of the ATP obtained during aerobic respiration results from oxidative phosphorylation.c. Oxidative phosphorylation resulting from 1 glucose molecule returns about 12 ATP molecules.d. The total yield of ATP molecules per glucose molecule is around 32.

Some friends are trying to make wine in their basement. They"ve added yeast to a sweet grape juice mixture and also have actually permitted the yeast to flourish. After numerous days they discover that sugar levels in the grape juice have dropped, however there"s no alcohol in the mixture. The a lot of most likely explanation is thata. the yeastern used the alcohol as a carbon source.b. the mixture requirements even more oxygen, bereason yeastern need oxygen to break dvery own sugar and also obtain enough power to create alcohol.c. the mixture requirements less oxygen, because yeastern only produce alcohol in the lack of oxygen.d. the mixture requirements more sugar, because yeastern need the majority of energy prior to they can begin to create alcohol.
