The small molecule acetylcholine acts to signal different cellular responses in many different cell types, including skeletal muscle cells, heart muscle cells, cells lining blood vessels, liver cells, and pancreatic cells. in each case, there is a membrane receptor that specifically binds acetylcholine. upon binding, acetylcholine triggers a to elicit a specific cellular response.

signal transduction pathway

Explanation:

The signal transduction pathway occurs when a molecule triggers an orderly sequence of chemical reactions within a cell. All of these reactions are mastered by enzymes, after a molecule activates the first reaction through signals or stimuli. Reading the text in the question above, we can see that, after binding, acetylcholine triggers a signal transduction pathway, creating a sequence of reactions, to elicit a specific cellular response.

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.  

economic impact of malaria is estimated to cost africa $12 billion every year. this figure factors in costs of health care, absenteeism, days lost in education, decreased productivity due to brain damage from cerebral malaria, and loss of investment and tourism.
