During periods of intense exercise, cells do not receive enough oxygen to perform the normal process of aerobic cellular respira
tion. As a result, the cells resort to anaerobic respiration, which produces only 1/20th of the energy produced during the aerobic process. This alternative version of cellular respiration produces lactic acid as waste, which results in muscle soreness. Which of the following statements does the above information support? A
Cellular respiration is affected by sugar production.
B.
Cellular respiration is affected by cell hydration.
C.
Cellular respiration is affected by the availability of reactants.
D.
Cellular respiration is affected by temperature.
Cellular respiration begins with a process that divides the glucose within the cells making it readily available as a source of energy. This process can occur without oxygen (anaerobic respiration) or in the presence of oxygen (aerobic respiration). Anaerobic respiration generates more excess waste (lactate) than aerobic . Besides, high levels of lactate build within the muscle cells. Excess lactate slows the cellular respiratory process and is experienced as a burning sensation in the muscles if exercise continues.
olecules can diffuse across membranes via transport proteins, or they can be aided in active transport by other proteins. Organelles such as the endoplasmic reticulum, Golgi apparatus, mitochondria and peroxisomes all play a role in membrane transport.
The point of cellular respiration is to get energy for the cell. ATP is the "energy currency" of the cell that enables it to function at normal levels. In cellular respiration, a process called <u>glycolysis</u> breaks down glucose to obtain large amounts of ATP.
