Answer:
The major energy source for red blood cell is glucose. Due to lack of enzymes in mitochondria of most other cells of mature erythrocyte, the red blood cells cannot depend on aerobic glycolysis,as in the Kreb's cycle to obtain energy from glucose. Therefore Embden- Meyerhof pathway use to process glucose into ATP anaerobically. In addition to adenosine triphosphate production, this pathway maintains pyridine nucleotides in a reduced state. Nicotinamide adenine dinucleotide reduced twice in the pathway. First reduction occurs when NAD combines with glyceraldehyde -3- phosphate to form 1,3- diphosphogylcerate. Then reduced NAD along with lactate dehydrogenase catalyzes the conversation of pyruvate to lactate.
why does glucose meatabolism end with lactate in the mature RBC instead of with CO2 and...
2a. What is the net yield of ATP from 1 glucose molecule metabolized anaerobically to lactate? b. Why is the end product of anaerobic glycolysis in cells lactate, rather than pyruvate?
5. The oxidation of glucose is usually written as: CcH 1206 + 602 → 6 CO2 + 6 H2O Is this an accurate depiction of how glucose is oxidized in cells? Why or why p 5.

Please show calculations, thank you! QUESTION 5 Glucose (C&H1206) 2 Lactate (C H,Os) o Compare anaerobic and aerobic catabolism of glucose under standard conditions. The net reactions are shown on the right: He' ~-194 kJ/mol (99%) TAS® ~ +2 kJ/mol ( 1%) ΔGo, ~-196 kJ/mol (a) List possible reason(s) for the aerobic catabolism of glucose yielding so much more ATP than anaerobic catabolism of glucose. Glucose (CH 602 - 6 CO2+ 6 H2O o ΔΗΡ. ~-2800 kJ/mol (98%) T So,...
Why is glucose used FIRST by bacteria even when its scarce in the environment. Why does catabolite repression favor glucose instead of lactose. Provide a simple explanation.
QUESTION 15 Which of the following is EXERGONIC? 6 CO2 + 6H20 - glucose + O2 fructose 6-phosphate + ATP – fructose 1,6-bisphosphate + ADP (AG = -3.4 kcal/mol) glucose 6-phosphate + ATP – fructose 6-phosphate + ADP (AG = +0.5 kcal/mol) GDP - Pi GTP + H2O QUESTION 17 Fate(s) of pyruvate is(are) Check all that apply. formation of ethyl alcohol by yeasts formation of glucose by gluconeogenesis in liver cells production of ketone bodies formation of lactate under...
why does glucose enter and not exit the cell ?
actate Fermentation Alcoholic Fermentation Description Starts with glycolysis Generates pyruvate at the end of glycolysis Does not generate any CO2 Starts with six-carbon glucose and ends with two molecules of a two-carbon by-product 000 Many people enjoy sugary soda pop because it is fizzy. This fizziness is the result of pressurized gas that is artificially added during the manufacturing process. People have also enjoyed the fizziness of beer and sparkling wine for thousands of years, but the gas in beer...
Question 1 A-C Question 2 Question 1: Glycolysis represents only very limited oxidation of glucose into pyruvate, and may be followed up by fermentation involving reduction of pyruvate, not further oxidation. Part A. (4 points) Explain how one molecule of NAD+ plays important roles in both parts of the above paired reactions, specifically mentioning how it is involved in both oxidation and reduction Part B. (4 points) The enzymes involved in the reduction of pyruvate to lactate or ethanol have...
1.) why does the metabolism of glucose take place in so many steps?
