Answer:
The answer to the question: What are the two mechanisms that microorganisms use to generate ATP, would be: anaerobic and aerobic cellular respiration.
Explanation:
ATP (Adenosine Tri Phosphate) is in general terms, the powerhouse of all molecules. Its presence in any organism who need energy to be able to function, is vital and without it, there is simply no energy for a cell, be it eukaryotic, or prokaryotic, to function. ATP can be generated then through two mechanisms, both dependent on one simple molecule: glucose. While the first mechanism, anaerobic generation of ATP, received that name because the process of phosphorylation does not require the presence of oxygen to happen, the second one, also known as cellular respiration, depends entirely on oxygen to be able to yield the most molecules of ATP from glucose.
Answer:
In general, epithelial tissues are classified by the number of their layers and by the shape and function of the cells. The three principal shapes associated with epithelial cells are squamous, cuboidal, and columnar. Squamous epithelium has cells that are wider than their height (flat and scale-like).
