Textbook Question
Chapter 6, Problem 16CTQ
Does physical exercise involve anabolic and/or catabolic processes? Give evidence for your answer.
Expert Solution & Answer
Trending nowThis is a popular solution!
Students have asked these similar questions
investigate lactic accumulation and the pH change in the muscle cells.
The following are your guide questions:
1) What are the conditions that will promote the formation of lactic acid?
2) What is the effect of elevated lactic acid in the muscle cells, blood, and heart muscle?
3) What is the effect of the pH change (being acidic) in the muscle cells when glucose or fats are used as energy sources?
You have to support your report with information coming from books or sources coming from the internet but make sure to get it from credible sites. You may also place pictures or illustrations or even chemical equations in your report. More importantly, make the information simple, concise, and straight to the point. Do not forget to cite the references using the APA format
Catabolism and anabolism are major types of metabolic activity.
True
False
Give two SPECIFIC examples of when, where, and why temperature and pH are important to the activity of enzymes in your body.

- Discuss briefly but concisely the importance of the following metabolic pathway. D. Gluconeogenesisarrow_forwardA 16-year-old female is recently diagnosed with a deficiency of muscle glycogen phosphorylase. She and her family are concerned and ask the following questions. Based on what you know about skeletal muscle glycogenolysis and muscle metabolism, please respond to each question with a thoughtful answer that describes the metabolism in these various scenarios in language that your patient will understand, while also being sure to include the role of the relevant metabolic pathways, specific enzymes, and stimulus for their activity: I’m not sure I understand the issue. Can you explain how muscle glycogen is used normally during exercise? I really like to take long walks; will Istill be able to do this with my friends? As a result of this deficiency, will I need to get up at night to eat to maintain my blood glucose levels? Do I need to worry about producing excessive lactate during intense anaerobic exercise?arrow_forwardExplain how the structure of glycogen makes it ideals as a fuel storage compound.

- In hepatocytes, the enzyme glucokinase catalyzes the ATP-coupled phosphorylation of glucose. Glucokinase binds both ATP and glucose, forming a glucose-ATP-enzyme complex. The enzyme then transfers the phosphoryl group directly from ATP to glucose. Select the advantages of phosphoryl group transfer compared to hydrolysis and subsequent phosphorylation? ATP hydrolysis is thermodynamically unfavorable compared to group transfer. Glucokinase increases the transition state energy, favoring glucose phosphorylation. The process takes advantage of the high phosphoryl group transfer potential of ATP. Reaction intermediates do not need to be present in excess. Incorrectarrow_forwardThe catalytic activity of enzymes depends on the presence of appropriate environmental conditions. Pepsin is a digestive enzyme found in the stomach and facilitates the digestion of large proteins. If pepsin is removed from this acidic environment of the stomach and is instead placed in a more basic environment, it will cease to function. Describe the specific effect that a change in environmental pH will have on pepsin and explain how this change can lead to inhibition of its catalytic activity. Respond in 4 to 6 complete sentences.arrow_forwardPlease handraw this graph with all the necessary detailed information: Imagine that I text enzyme rate for four different temperatures: 10 degrees celsius, 20 degrees celsisus, 30 degree celsius, and 40 degree celsius, in separate tubes. The enzyme appears to work faster as temperature increases, but completely ceases activity at 40 degrees celcius. Sketch a graph to show this outcome, but here you will graph product formation (nmoles/mL) vs. time (minutes). The graph should be 4 lines and HANDDRAWN. Include a legend if necessary. You do not need precise quantitivate values, but most show the correct trends on the graph.arrow_forward
