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
Give two SPECIFIC examples of when, where, and why temperature and pH are important to the activity of enzymes in your body.
Define aerobic and anaerobic metabolism. What happens when there is insufficient oxygen? Make sure to include lactate in your answer.

- A 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_forwardIn 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_forwardWhat other molecules (besides sugars) serve as a source of energy for our bodies?
