Epinephrine causes muscles to contract and the heart and lungs to increase respiration and blood flow. In combination with epinephrine causing glucose production and secretion from the liver, how does epinephrine elicit a system wide response? Multiple Choice A.) Glucose provides energy for muscle contractions, which are stimulate by high concentrations of oxygen. Oxygen is provided by the increase in respiration and blood flow. B.) Glucose provides energy for muscle contractions, resulting in high levels of pyruvic acid. The pyruvic...

New biosensors, applied like a temporary tattoo to the skin, can alert serious athletes that they are about to hit the wall and find it difficult to continue exercising. These biosensors monitor lactate, a form of lactic acid, released in sweat during strenuous exercise. Which of the statements below is the best explanation of why athletes would need to monitor lactate levels? Select one: a. During strenuous exercise, oxygen is scarce and cell switch from fermentation to aerobic respiration. b....

During exercise when the body lacks an adequate supply of oxygen to support energy production, the pyruvate that is produced from the breakdown of glucose is converted into lactate. High lactate levels can lead to acidity in the muscle cells as some of the lactate hydrolyzes to lactic acid. The dissociation of lactic acid to lactate is shown in the reaction. Lactic acid has a p?a of 3.86. Lactic acid dissociates into the lactate ion and a hydrogen ion. The...

6. The cells of some organisms other than animals and yeast (such as bacteria) carry out fermentation using molecules other than pyruvate, which are similarly reduced as pyruvate is. What is the goal of fermentation and why is the reduction of some molecule (whether it be pyruvate or some other molecule) important to achieve this goal? What would happen if the organism is unable to carry out this fermentation? 7. You want to study the enzymes that function in glycolysis,...

Can someone please help with questions ii-vi?
6. Many types of cancerous tumors have cells with a high dependence on glycolysis for generating the ATP needed for growth. Even in the presence of oxygen, these cells use glycolysis and lactate fermentation as their main source of ATP. i.) Give a balanced reaction for the reaction catalyzed by the enzyme lactate dehydrogenase (LDH). Give the structures of pyruvate and lactate, and add the names of any additional reactants or products needed...
