Choose all of the molecules that are made in acetyl-CoA formation and the citric acid cycle that are important to note.      NADH     FADH2     CO2     ATP     pyruvate     glucose

The most regulated enzyme in glycolysis is a   Hexokinase b   G3P Dehydrogenase c   Pyruvate Kinase d   Phosphofructokinase

Which of the following Krebs cycle enzymes generates a molecule of FADH2 from FAD? a-ketoglutarate dehydrogenase pyruvate dehydrogenase isocitrate dehydrogenase malate dehydrogenase succinate dehydrogenase

When pyruvate dehydrogenase complex is phosphorylated, it is (active or inactive)

Below is an image showing how cellular respiration is regulated. Imagine someone ingested a toxin that prevents pyruvate from entering the mitochondria. Which of the following statements is true? Inhibits ATP Glucose GLYCOLYSIS Copyright 2018 Pearson Canada Inc. Fructose 6-phosphate Phosphofructokinase Fructose 1,6-bisphosphate Pyruvate Acetyl COA CITRIC ACID CYCLE Oxidative phosphorylation AMP I Stimulates Inhibits Citrate The amount of citrate in the cell would decrease, leading to a decrease in the activity of phosphofructokinse. The amount of citrate in the cell would increase, leading to a decrease in the activity of phosphofructokinse. The amount of citrate in the cell would decrease, leading to an increase in the activity of phosphofructokinse. The amount of citrate in the cell would increase, leading to an increase in the activity of phosphofructokinse.

Which of the following is the third step of Citric Acid Cycle? Select one: a. Succinyl-CoA becomes Succinate and forms one ATP molecule and Coenzyme A-SH b. Pyruvate is decarboxylated to become acetyl-CoA producing NADH and Carbon dioxide c. Isocitrate and then decarboxylated and oxidized to produce alpha-ketoglutarate, Carbon dioxide and NADH d. alpha-ketoglutarate is oxidized and decarboxylated to produce Succinyl-CoA, Carbon dioxide and NADH e. Succinate is oxidized to become fumarate forming FADH2 f. Oxaloacetate combines with the acetyl from acetyl-CoA to produce Citric acid(citrate) g. Citrate is rearranged to become Isocitrate h. Malate is oxidized to become oxaloacetate forming NADH i. Fumarate is combined with water to become Malate

If TWO acetyl CoA enter the citric acid cycle, for each glucose we started with, then how many of each product listed below do we get. _____ ATP _____ NADH _____FADH2 _____ CO2
