Question 1 Answer: 3
Catabolism can be broken down into 3 main stages.They are: Stage1-Stage of Digestion Stage2- Release of energy Stage3- Energy Stored
Catabolism can be considered to be the sum of stages. Question 1 options: 1 2 3...
3 20 The conversion pyruvate to either ethanol or lactate occurs A. when there is an abundance of pyruvate but a deficiency of onygen B. when there is an abundance of BOTH pyruvate and oxygen C. when there is a deficiency of BOTH pyruvate and oxygen D. for the regeneration of NADH so that hydrolysis of ATP can continue to fuel the glycolysis pathway Explain how gluconeogenesis differs from gtycolysis 21 Gluconeogenesis is simply the reverse of all 10 steps...
Question 5 1 pts What is the main purpose of the Kreb's cycle (also known as the TCA or Citric Acid cycle) To produce ATP from the energy stored in acetyl-CoA To oxidize pyruvate and produce NAD and FADH2 To recycle NADH for use back in glycolysis To produce carbon dioxide by the reduction of pyruvate To produce NADH/FADH2 from the oxidation of acetyl-CoA
Question 3 1 pts How many of the molecules below are products of glycolysis? ATP ADP NADH Pyruvate Acetyl-CoA CO2 FADH2 Water Oxygen Glucose FADH NAD
This is a biochemistry question i need answers to 6-12
What is the purpose of fermentation of pyruvate to lactate or ethanol? to produce additional ATP to provide a precursor for lactose synthesis to regenerate NAD* for glycolysis to prevent pyruvate from entering the TCA cycle none of the above Pyruvate kinase catalyzes what reaction? conversion of phosphoenol-pyruvate to pyruvate phosphorylation of pyruvate to 3-phosphoglycerate conversion of pyruvate to acetaldehyde and CO_2 conversion of pyruvate to lactate conversion of pyruvate...
What is the reducing agent (or electron donor) in the following reaction? Pyruvate + NADH + H^+ rightarrow Lactate + NAD^+ A. oxygen B. NADH+H^+ C. NAD^+ D. lactate E. pyruvate Reactants capable of interacting to form products in a chemical reaction must first overcome a thermodynamic barrier known as the reaction's A. entropy B. heat content. C. activation energy. D. endothermic level. E. free-energy content. What does the chemiosmotic process in mitochondria involve? A. establishment of a proton gradient...
QUESTION 2 The pyruvate dehydrogenase complex O a. leads to the formation of coenzyme A (COA). Ob.catalyzes key reactions in glycolysis. Oc oxidizes NADH to NAD+. d. can be found in the mitochondria of eukaryotic cells.
Question 26 1 pts Which is a correct statement about the preparatory reaction? It connects glycolysis directly to the electron transport chain. 02 is given off. Pyruvate is converted to lactate. NAD+ goes to NADH + H+ as acetyl-CoA forms. The reaction occurs once per glucose molecule.

Select all that apply. Identify the reaction(s) of glycolysis inhibited by ATP □ glyceraldehyde-3-phosphate → 1,3-bisphosphoglycerate phosphoenolpyruvate +pyruvate 3-phosphoglycerate ~2-phosphoglycerate 1) fructose-6-phosphate→ fructose-1,6-bisphosphate . glucose glucose-6-phosphate Select all that apply. Alcohol fermentation: consumes ATP as it produces ethanol. O produces carbon dioxide begins as pyruvate is decarboxylated to acetaldehyde in a reaction catalyzed by alcohol dehydrogenase m regenerates NAD requires the enzyme alcohol dehydrogenase, In the figure below, what is the reaction occurring at the location...

QUESTION 2 non-carbohydrate precursors for gluconeogenesis are lactate. glycerol, and amino acids. Your textbook (T ymoczkode Fig 17.1: Bergße Fig 1624) shows where these metabolites enter into the gluconeogenic pathway. Evaluate the energetic cost to make one glucose molecule from one 1.5 ATP equlvalents per cytoplasmic molecule of each precursor in terms of ATP equivalents (total ATP and GTP directly consumed plus NADH oxidized). ATP equivalents consumed to make 1 glucose Aspartate...
