Answer: B. Speed up the chemical reaction
Explanation: Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.
I’ll like to answer but Where the question ?
I just did this BTW. The correct answer is A.) Nuclear fusion is the correct answer. Nuclear fission is what we use today in nuclear power plants, a great deal of radioactive waste, the other are by products of this process. Nuclear fusion releases a great deal of energy with a little radioactivity, but the problem is ignition temperatures; but maybe someday.
Answer:
The coughing reflex kicks in, only if the epiglottis reflex fails to. If the coughing reflex fails then the Heimlich maneuver may be needed.
Answer:
Under anaerobic condition pyruvate is converted into lactate.
Explanation:
Human muscles use both anaerobic and aerobic respiration for the production of ATP. During the starting of intense activity, the oxygen supply is not enough to provide instant energy to the muscle, therefore, muscles use anaerobic respiration to generate ATP.
During anaerobic respiration, muscle do not use oxygen to burn glucose. During anaerobic respiration in muscles, the glucose is converted into pyruvate and then this pyruvate gets convert into lactate and this process is called lactic acid fermentation. In this process, 2 ATP are produced.
