In eukaryotic cells, the citric acid cycle occurs in the _____________.

QUESTION 37 Key enzymes in glycolysis and the Krebs cycle are allosterically regulated. Which of the following is FALSE? O a. The main control point of glycolysis is the enzyme phosphofructokinase. Ob. The main control point in the citric acid cycle is isocitrate dehydrogenase Oc. Isocitrate dehydrogenase is inhibited by ATP or NADH. O d. Phosphofructokinase is activated by citrate and ATP. Oe. If ATP levels are high and the citric acid cycle shuts down, acetyl CoA is diverted to the synthesis of fatty acids for storage lick Save and Submit to save and submit.

Question 7 Please click here to access the Unit 6 lab experiment video. Please consider the B1 extractions with 1 M aqueous sulfuric acid, which is described in the Unit 6 lab instructions document - Under the acidic extraction conditions with aqueous sulfuric acid, benzaic acid will be found predominantly in what form and in which phase (ether or aqueous)? Benzoic acid is in its protonated form and can predominantly be found in the upper ether phase. O Benzoic acid is in its protonated form and can predominantly be found in the lower aquecus phase. O Benzoic acid is in its deprotonated form las socium benzoate salt) and can predaminantly be found in the upper ether phase. O Benzoic acid is in its deprotonated form (as sodium benzoate salt) and can predominantly be found in the lower aquenus phase.

QUESTION 1 You have a crude lysate sample (CL) containing a mixture of six proteins (1, 2, 3, 4, 5, ẞ- galactosidase), and your goal is to obtain purified ẞ-gal. Some characteristics of these proteins are shown in the table below. Protein Alcohol dehydrogenase Carbonic anhydrase Insulin B chain Phosphorylase B Glutamic dehydrogenase B-galactosidase Concentration of ammonium sulfate (AS) required for precipitation Molecular Weight (kDa) Isoelectric point (pl) 45% 38 3.7 80% 65% 20% 30% 45% 28 4.8 4 5.3 98 68 49 9.5 115 5.3 You begin your purification by performing an ammonium sulfate (AS) precipitation. You add the appropriate concentration of AS to your CL sample, incubate overnight at 4°C, then centrifuge to generate a supernatant (AS-S) and pellet (AS-P). What concentration of AS will you use to precipitate ẞ-galactosidase? O 20% O 30% O 45% 65% O 80%
