Many cells in the human body maintain an electric potential difference across their cellular membranes, typically through the use ion-specific pumps and channels that generate an excess of negative charges on the inside of the cellular membrane and an excess of positive charges on the outside. Let us estimate the total energy stored in the human body by this type of charge separation.

- Select the correct statement regarding electrochemical gradients. Thermodynamically, electrochemical gradients will maintain their relative concentrations across both sides of the membrane. The cytoplasmic side of the cell membrane has a net positive charge relative to the extracellular side. Ions can freely pass through the cell membrane. Electrochemical gradients are sources of potential energy due to the differences in concentrationsand charge across both sides of the cell membrane. Select the correct statement(s) about transfer RNAs. Codon recognition occurs through specific base-pairing by the anticodon arm. Amino acids are linked to the T-loop. They are transcribed by RNA Polymerase III. There is strict matching requirements at the third position, else the tRNA cannot interact with the codon.At different glucose concentrations (2 mol of glucose, 4 mol of glucose, 8 mol of glucose), at what time, in milliseconds, was the increase in ATP the greatest and how does this affect the potential (mV) graph? I am having hard time analyzing this thank you______________ is a molecule that forms when a phosphate compound splits off from a molecule of _______________, releasing energy that can now do work for the cell. This molecule, when formed due to this removal of a phosphate compound, can be thought of as a "dead battery". It can become "recharged" when the phosphate compound is added back onto this molecule. Question 1 options: Reduced nicotinamide adenine dinucleotide (NADH), adenosine triphosphate (ATP) None of the other answers are correct. Sucrose, glucose Zymase, pyruvate Adenosine diphosphate (ADP), adenosine triphosphate (ATP) Adenosine triphosphate (ATP), acetaldehyde Adenosine triphosphate (ATP), adenosine diphosphate (ADP) Lactate, ethanol

QUESTION 21 The process of osmosis measures the permeability of water across a semipermeable membrane. Considering this, define what hypotonic, isotonic, and hypertonic solutions are.A 75 kg person doing light work requires about 3000 kcal of food energy perday, 40% of which is actually used by the body’s cells. (The other 60% is lostas heat and in waste products.) Before being used by the cells, effectively allof this energy is stored in ATP, which is then cleaved into ADP and PO3−2 , with the release of 12.5 kcal per mole of ATP.(a) How many moles of ATP are turned over per day in this fashion? Whatmass of ATP does this correspond to? (The molecular weight of ATP is507 g/mol.)(b) The body actually contains approximately 5 g ATP. Estimate the averagerecycle time for an ATP molecule. You see that it is much more efficientto reuse ADP rather than to synthesize it de novo (from scratch).A 70-kg adult human (154 lb) could meet his orher entire energy needs for one day by eating 3 moles ofglucose (540 g). (We do not recommend this.) Each mol-ecule of glucose generates 30 molecules of ATP when it isoxidized to CO2. The concentration of ATP is maintained incells at about 2 mM, and a 70-kg adult has about 25 litersof intracellular fluid. Given that the ATP concentrationremains constant in cells, calculate how many times perday, on average, each ATP molecule in the body is hydro-lyzed and resynthesized.
- Use the appropriate equation to calculate the free energy change for the movement of Nat into the depolarized nerve cell where the membrane potential is +50mV and the Nain/Naout ratio is 7.3/1. Assume the temperature is 37°C. Stop! For full credit: 1. Enter your answer in kJ, kilojoules. 2. Do not put units in the box. 3. Round your answer to the nearest tenth. If your calculator permits, do not round until the end for the sake of continuity. 4. If your answer is negative, include the sign and number with no space.The synthesis of ATP by oxidative phosphorylation, using the energy released by movement of protons across the membrane down their electrochemical gradient, is an example of which of the following processes?The 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+

Answer questions afterwards.What is the advantage of using ATP as a common energy source?Another way of asking this question is, “Why does ATP provide anadvantage over using a bunch of different food molecules?” For example,instead of just having a Na+/K+-ATPase in a cell, why not have manydifferent ion pumps, each driven by a different food molecule, like aNa+/K+-glucosase (a pump that uses glucose), a Na+/K+-sucrase (a pumpthat uses sucrose), a Na+/K+-fatty acidase (a pump that uses fatty acids),and so on?
