Question

purpose: what are the affects of anaerobic respiration on your muscles? background: under normal conditions muscles utilize oxygen (aerobic respiration) to make atp from glucose. this process is very efficient and produces 38 atps for each molecule of glucose. carbon dioxide and water are the by - products of this reaction. when muscles undergo rigorous exercise, they require more oxygen to make atp than the blood can supply. at this point the muscle is forced to produce atp without oxygen (anaerobic respiration). anaerobic respiration produces only 2 atps for each molecule of glucose. the product of this reaction is lactic acid. the advantages of anaerobic respiration are that the muscle cell can make atp without oxygen, and it can make atp very quickly. this a particular advantage when lifting heavy objects. the big disadvantage to anaerobic respiration is that it produces lactic acid which gives muscles a temporary burning sensation. muscle fatigue results when the demand for atp is greater than the rate at which atp can be produced in the muscle fibers. as a consequence, atp levels are too low for muscle fibers to produce their maximum force contraction. under condition of extreme fatigue, muscles become incapable of contracting or relaxing. today you will experience the use of aerobic respiration and anaerobic respiration by the muscle fibers in your fingers. you will experience the production of lactic acid and the sensation it produces in your muscles. the lab will demonstrate how your body used the resources available to provide you with the energy you need to do work. vocabulary: aerobic respiration, glucose, atp, anaerobic respiration, muscle fatigue, lactic acid refining understanding: aerobic respiration anaerobic respiration necessary requirements reactants advantages disadvantages

Explanation:

• Necessary Requirements:
• Aerobic Respiration: Requires oxygen.
• Anaerobic Respiration: Does not require oxygen.
• Reactants:
• Aerobic Respiration: Glucose and oxygen ($C_6H_{12}O_6 + 6O_2$).
• Anaerobic Respiration: Glucose ($C_6H_{12}O_6$).
• Advantages:
• Aerobic Respiration: Very efficient (produces 38 ATP per glucose molecule).
• Anaerobic Respiration: Can make ATP without oxygen and quickly.
• Disadvantages:
• Aerobic Respiration: Needs a continuous oxygen supply (may be limited during intense exercise).
• Anaerobic Respiration: Produces lactic acid (causes temporary burning sensation) and is less efficient (produces 2 ATP per glucose molecule).

Answer:

	Aerobic Respiration	Anaerobic Respiration
Reactants	Glucose ($C_6H_{12}O_6$) and oxygen ($O_2$)	Glucose ($C_6H_{12}O_6$)
Advantages	Very efficient (38 ATP per glucose)	Can make ATP without oxygen and quickly
Disadvantages	Needs continuous oxygen (may be limited in intense exercise)	Produces lactic acid (burning sensation), less efficient (2 ATP per glucose)
