CELL RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The buildup of waste products in muscle cells that are active might cause
A
digestion
B
cellular respiration
C
increased fatigue
D
decreased heart rate
Explanation: 

Detailed explanation-1: -When waste products build up within muscles, they can cause the muscle to fatigue and weaken more easily, resulting in increased chances of injuries occurring. When the removal of waste products is increased, the level of metabolic wastes, such as lactic acid, within the muscles is reduced.

Detailed explanation-2: -Key points. Lactic acid is the waste product produced during anaerobic respiration. Running fast can lead to a build-up of lactic acid in your muscles, causing cramp. Lactic acid also causes tooth decay.

Detailed explanation-3: -Lactic acid is mainly produced in muscle cells and red blood cells. It forms when the body breaks down carbohydrates to use for energy when oxygen levels are low. Times when your body’s oxygen level might drop include: During intense exercise.

Detailed explanation-4: -Metabolic Waste is produced by our cells every day, even our muscles produce metabolic waste due to everyday function. It is the build-up of toxins in the body which cannot be used and therefore become toxic and need to be excreted from the body through urination, sweating and exhaling.

Detailed explanation-5: -When taking part in exercise, there is a greater cardiac output because the athlete requires more blood and oxygen to be transported to the working muscles. The increase in the amount of blood also helps with the removal of waste products such as lactic acid and carbon dioxide.
