(a)
Interpretation:
The balanced equation involved in the transformation of aspartate into glucose through an intermediate oxaloacetatemolecule and coenzymes should be written.
Concept introduction:
Transamination is also known as an amino transfer. It is a
(b)
Interpretation:
The balanced equation involved in the transformation of aspartate into oxaloacetate through an intermediate fumarate molecule should be written.
Concept introduction:
The urea cycle is a series of biochemical reactions which involve the formation of urea (NH2)2CO from the ammonia (NH3). It is also known as the ornithine cycle. It helps in the excretion of toxic ammonia by converting into urea. This cycle takes place in ureotelic organisms.

- X INCORRECT; see section 13.1 Enzymes occasionally display weak "“side" activities. Draw the structure of the product (other than ADP) of the reaction that results when pyruvate kinase, operating in reverse, uses lactate as a substrate. For your structure: 1. Do not include primary or secondary hydrogens. CH2 HO OH Edit Drawingarrow_forwardDraw Gluconeogenesis. Please make sure to state all the enzymes and co-factors for each step of the pathway.arrow_forwardLong explanations are not needed. Direct answers would suffice. a. Ribose-5-phosphate is produced by oxidative decarboxylation of 6-phosphogluconate catalyzed by the enzyme glucose-6-phosphate dehydrogenase. I. True II. False b. The pentose phosphate pathway occurs in the mitochondrion of tissues actively engaged in synthesis of fatty acids. I. True II. Falsearrow_forward
- Long explanations are not needed. Direct answers would suffice. ***kind of in hurry so having the answer asap would greatly be appreciated, thank you :)) a. The first step in the pay-off phase of glycolysis is the oxidation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate. i. True ii. False b. Phosphofructokinase-1, the major flux-controlling enzyme of glycolysis is inhibited by _______. i. AMP ii. ATP iii. ADP iv. phosphoenol pyruvatearrow_forwardLong explanations are not needed. Direct answers would suffice. a. Transketolases catalyze two-carbon fragment transfer from sedoheptulose-7-phosphate to xylose-5-phosphate. i. True ii. False b. High concentration of NADPH increases the rate of the pentose phosphate pathway by stimulating glucose-6-phosphate dehydrogenase. i. True ii. Falsearrow_forwardIn full details. Explain the significance of redox potentials formed by redox pairs in the electron transport chain.arrow_forward
- Hi, help please. Discuss each method of regulating phosphofructokinase below as indicated by the circle. Discuss 1.) The type of regulation occurring, 2.) What compound or condition performs the regulation, 3.) How/why it influences the enzyme activity.arrow_forwardClosely related. Pyruvate dehydrogenase complex and a-ketoglutarate a-ketoglutarate dehydrogenase complex are huge enzymes consisting of three discrete enzymatic activities. Which amino acids require a related enzyme complex, and what is the name of the enzyme?arrow_forwardRequired partner. Aminotransferases require which of the following cofactors: a. NAD+/NADP+NAD+/NADP+ b. Pyridoxal phosphate c. Thiamine pyrophosphate d. Biopterinarrow_forward

What energetic barrier prevents glycolysis from simply running in reverse tosynthesis glucose? What is the energetic cost to overcome this barrier?arrow_forwardLong explanations are NOT NEEDED. I pretty much have an idea already about this lesson, I would just like to see if my answers are correct, if it's wrong then kindly correct and just add a short explanation. ATP accounting. Consider 1 molecule of the sucrose (monomeric units: glucose and fructose) that will undergo complete oxidation. a. Number of pyruvate molecules after glycolysis is 4.b. Net ATP produced in glycolysis only (via substrate-level phosphorylation) is 2.c. Number of NADH produced using the pyruvate dehydrogenase complex reaction is 1.d. Number of NADH and FADH2 produced from Krebs cycle is 12 and 4 respectively.e. Net ATP produced (complete oxidation via Malate aspartate shuttle) is 64.arrow_forward
