topic 2: MUSCLES AND ENERGY

Picture[Source: https://steemit.com/steemstem/@co-co/medicalmonday-1-from-the-banana-to-energy]
Muscles use the stored chemical energy from food we eat and convert that to heat and energy of motion (kinetic energy). Energy is required to enable growth and repair of tissue, to maintain body temperature and to fuel physical activity. Energy comes from foods rich in carbohydrate, protein and fat.

Define cellular respiration
Explain the process of cellular respiration, including the roles of glucose, oxygen, and ATP in energy production.
Analyze the relationship between exercise and cellular respiration, including how exercise affects the body's oxygen and glucose needs.
Evaluate the impact of exercise on the cardiovascular and respiratory systems, including changes in heart rate, breathing rate, and blood pressure.
State the concept of VO2 max and its role in measuring aerobic fitness.
Compare and contrast the different types of exercise, including aerobic, anaerobic, and resistance training, in terms of their energy requirements and impact on the body.
Explain the concept of lactate threshold and its relationship to exercise intensity and fatigue.
Evaluate the use of scientific models as a means of understanding scientific concepts
Explain why our muscles get tired when we exercise?
​Explain the concept of blood glucose regulation and its importance in maintaining proper physiological function.
Explain the role of insulin and glucagon in regulating blood glucose levels, including how they are produced and released by the pancreas.
​Explain the relationship between blood glucose levels and insulin secretion, including the feedback loop that regulates insulin production.
​Analyze the effects of different foods and macronutrients on blood glucose levels, including carbohydrates, proteins, and fats.
Discuss the effects of physical activity and exercise on blood glucose levels, including how it can improve insulin sensitivity and help regulate blood glucose levels.
Draw a feedback mechanism for blood glucose regulation

This video covers the effects of exercise on the body, including details about respiration and the oxygen debt.
This video focuses on general functions of biomolecules. The biomolecules: carbs, lipids, proteins, and nucleic acids, can all can have important functions in the body
Beneath your ribs, you’ll find, among other things, the pancreas -- an organ that works a lot like a personal health coach. Emma Bryce explains how this organ controls your sugar levels and produces a special juice that releases the nutrients from your food to help keep you in the best possible shape.
n, you will learn about how your blood glucose level is regulated (or controlled) by two important hormones – insulin and glucagon, via a negative feedback system.​
For decades, lactic acid has taken the blame for the muscle pain you feel when you exercise - but does it really deserve its bad reputation?
