What would most likely promote increased rates of glycolysis? Select one: a. a higher concentration of Na in the environment compared to cells b. a higher concentration of K in cells compared to the environment c. a high concentration of ATP in cells d. a low concentration of ATP in cells e. presence of oxygen in cells

The cell senses ATP is not being produced. What immediate effect will this have on the rate of glycolysis occurring in the cell? What will happen to the levels of pyruvate? A. Glycolytic rates will decrease: pyruvate levels will decrease B. Glycolytic rates will increase: pyruvate levels will increase C. Glycolytic rates will increase: pyruvate levels will decrease D. Glycolytic rates will decrease: pyruvate levels will increase     2. How will the cell shift its metabolic processes in response to the level of pyruvate and in order to produce ATP? A. It will shift from aerobic respiration to fermentation B. It will shift from aerobic respiration to anaerobic respiration C. It will continue with aerobic metabolism using oxygen in the cytosol to make ATP D. It will shift from anaerobic respiration to fermentation   3. Some of the symptoms the patient is experiencing are caused by acid-base imbalances in the extracellular fluid. Why would the patients blood become more acidic over a…

This is the question: Ethanol metabolism has been part of the human diet for centuries. Ethanol cannot be excreted and must be metabolized by the liver using the enzyme alcohol dehydrogenase in a two step reaction: Excess consumption of ethanol leads to the accumulation of NADH. What effect would a high concentration of NADH have on metabolic pathways and consequently the body. Choose as least two pathways to describe the effect.

The average cell at rest hydrolyzes 10,000,000 ATP molecules per second.You are studying the stem cell population found in intestinal Crypts.In the intestine there are s total 5*1011 cell.The stem cells have a 85% higher metabolism than an average resting cell.ATP hydrlysis yield 7.4 kCal/Mole ATP(Avogadro's number is 6.023*1023) How many Kcal of energy are used per day by this population of cells? Assuming 32 ATP per glucose oxidative metabolically how many moles of glucose are consumed per day?

Based on what you know about glycolysis and aerobic cellular respiration, explain the advantage in terms of ATP production of a healthy respiratory and cardiovascular system.

Which of the following which of the following reactions is an endergonic reaction that could occur in a cell, but only if coupled to the hydrolysis of ATP? ( delta G= -32 kJ/ mol)?

Which of the following statement about the enzyme thermodynamics is TRUE?   a. Enzymes increase the activation barrier (∆G cat) of the products b. Enzymes decrease the activation barrier (∆G cat) of the products c. Enzymes decrease the free energy (∆G) of the products d. Enzymes decrease the free energy (∆G) of the reactants e. Enzymes increase the activation barrier (∆G cat) of the reactants

a. What is the efficiency of the metabolic conversion of palmitic acid to ATP? b. Compute the number of grams of palmitic acid that would have to be metabolized to provide the heat to warm a swimmer from whose skin 61 g of water evaporates.

You treat cells with 2,4 dinitrophenol (DNP). This compound creates a temporary channel in the inner membrane of the mitochondria though the protons can move. Which of the following would you observe in these cells? Select all that apply The cells do not synthesize ATP in the presence of DNP The cells synthesize ATP in the presence of DNP The cells reduce oxygen in the presence of DNP The cells generate carbon dioxide in the presence of DNP

As you change the temperature from a low temperature to a high temperature what happens to the rate of an enzymatic reaction, in general terms?   A The reaction rate will steadily increase as the temperature increases.   B The reaction rate will steadily decrease as the temperature increases.   C The reaction rate will start low, then increase, and then decrease again as the temperature increases.   D The reaction rate will not change as the temperature increases.
