Answer:
E) can usually make enough ATP for skeletal muscle function
Explanation:
Glycolysis is the main process by which cells obtain energy. During glycolysis, glucose is fully oxidized to obtain ATP, this is the 'fuel' for cellular function. Glycolysis is oxygen dependant, meaning that in order to successfully complete the process, enough oxygen must be available.
There are a few exceptions in which glycolysis is unable to provide enough ATP, an example is strenuous exercise. In this case the speed of oxygen consumption is very high, therefore at some point the oxygen intake is not enough. There are several mechanisms that regulate the production of ATP. In case of strenuous exercise, different process are activated to supply the cell with the necessary energy to keep on functioning.
Among the latter mentioned processes, there is anaerobic production of the oxidation of lactate, that does not require oxygen. Other example is the usage of creatine phosphate to obtain energy. Therefore, muscular cells have many ways of obtaining energy, but this secondary mechanisms are only activated in specific situations.
A biotic factor is a living thing that has an impact on another population of living things or on the environment. Abiotic factors do the same thing, but they are non-living. Together, biotic and abiotic factors make up an ecosystem. To survive, biotic factors need abiotic factors.
Viruses reproduce by inserting their genetic code into the genetic code of a cell, from there, an active virus will copy itself over and over until that cell bursts, where the new viruses can repeat the process. Another type of virus inserts itself into the genetic code, but does not actively reproduce. It sits and waits for the cell to reproduce for it, by splitting in the way cells do.
Answer:
<em>Entamoeba histolytica</em>
Explanation:
<em>Entamoeba histolytica </em>is the causative agent of amebiasis (amebic dysentery). The pathogen enters the human body through consumption of contaminated water or food and enters the small and large intestines. <em>E. histolytica</em> targets the epithelium of large intestine and creates ulcers in it. <em>E. histolytica </em>enter the mucosa and submucosa of the intestine through these ulcers and leads to severe dysentery, that is amoebic dysentery.
