Your body makes NAD+ from two B vitamins, niacin and riboflavin. You need only tiny amounts of these vitamins. The U.S. Food and Drug Administration’s recommended dietary allowances are 20 mg daily for niacin and 1.7 mg daily for riboflavin. These amounts are thousands of times less than the amount of glucose your body needs each day to fuel its energy requirements. How many NAD+ molecules are needed for the breakdown of each glucose molecule? Why do you think your daily requirement for these substances is so small?
How much fat (in grams) would the body have to burn to produce the daily minimum
requirement of 40 kg ATP from ADP and phosphate? Assume that: 1. The fat is
metabolized completely to water and carbon dioxide. 2. The energy that is released
can be used entirely for ATP production. 3. Complete oxidation of 1 g of fat to water
and CO2 releases 9 kcal or 37 kJ. 4. The Delta G for ATP hydrolysis is -30.5 kJ/mol.
You will have to look up one more value online to answer this question, but you do
not need to know anything about lipid metabolism.
A) approx. 16 to 17 g of fat
B) approx. 65 to 66 g of fat
C) approx 22 to 23 kg of fat
D) approx. 267 to 268 g of fat
E) approx. 5 to 6 kg of fat
Which of the following factors favor fatty acid synthesis in liver cells when blood glucose levels are way higher than 10 mM?
a.high NADPH and high NADH
b low NADPH and low NADH
c low NADPH and low NAD+
d high NADPH and high NAD+

- Which of the following statements about glucose metabolism is correct? * Red blood cells can catalyse aerobic glycolysis because they contain oxygen bound to haemoglobin. Fructose cannot be used for gluconeogenesis in the liver. Glycolysis can proceed in the absence of oxygen only if pyruvate is formed from lactate in muscle. All of the reactions of glycolysis are freely reversible for gluconeogenesis. Red blood cells can only metabolise glucose by anaerobic glycolysis and the pentose phosphate pathway.arrow_forwardIndicate whether each of the following is a true or false statement regarding ATP. in cellular respiration, the most ATP is made by the Krebs cycle ATP is commonly used by cells to lower the amount of energy needed for reactions to occur the energy from anabolic reactions can be used to make ATP some ATP is required to break down glucose into pyruvic acid a phosphate group is added to ADP to make ATP Choose...

- The oxidation of sugar molecules by the cell takes place according to the general reaction C6H12O6 (glucose) + 6O2 → 6CO2 + 6H2O + energy. which of the following statements are correct? explain your answers. all of the energy produced is in the form of heat. none of the produced energy is in the form of heat. The energy is produced by a process that involves the oxidation of carbon atoms. The reaction supplies the cell with essential water. in cells, the reaction takes place in more than one step. many steps in the oxidation of sugar molecules involve reaction with oxygen gas. some organisms carry out the reverse reaction. some cells that grow in the absence of O2 produce CO2.arrow_forwardThe concentration of glucose in your circulatory system is maintained near 5.0 mM by the actions of the pancreatic hormones glucagon and insulin. Glucose is imported into cells by protein transporters that are highly specific for binding glucose. Inside the liver cells the imported glucose is rapidly phosphorylated to give glucose-6-phosphate (G-6-P). This is an ATP-dependent process that consumes 1 mol ATP per mol of glucose. Given the steady-state intracellular concentrations below, calculate the theoretical maximum concentration of G-6-P inside a liver cell at 37 °C, pH = 7.2 when the glucose concentration outside the cell (i.e., [glucoseloutside) is 5.0 mM: ATP = 4.7 mM; ADP = 0.15 mM; P, = 6.1 mM For: ATP + H,O ADP + P + H* AG" = -30.5 kJ/mol and G-6-P + H,0 -→ Glucose + P AG" = -13.8 kJ/mol The glucose phosphorylation reaction is ATP + glucosenside » ADP + glucose-6-phosphate + H+arrow_forward(b) How is ATP converted to ADP by glucose?

They are interchangeable energy carriers, allowing the cell to use whichever molecule is in greatest abundance as a source of energy. They both act as electron carriers in the cell. Both compounds function as mobile energy carrier molecules in a cell. Both molecules are oxidized by molecular oxygen (O2) in reactions that release energy for use by the cell. Both ATP and NADH function as reducing agents in metabolic reactions.arrow_forwardThe energy stored in one molecule of NADH is used to synthesize how many molecules of ATP?arrow_forward
