Questions

Cost Estimating - Developing an approximation of the costs of the resources needed to complete  project activities.

Cost Budgeting - Aggregating the estimated costs of individual activities or work packages to establish a cost baseline

Cost Control - Influencing the factors that create cost variances and controlling changes to the project budget.

There are 3 stages in cellular respiration. They are:

1. Glycolysis

2. Kreb's cycle

3. Electron transport chain

Here, Glycolysis produces only 2 ATP whereas Kreb's cycle produces no ATP. Electron transport chain of the cellular respiration produces the maximum ATP.

Fermentation is the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat.

The two most common types of fermentation are

(1) alcoholic fermentation (and) 

(2) lactic acid fermentation.

(1) Alcoholic fermentation : the type of fermentation in which ethyl alcohol is the main end product .This is very common in yeast (unicellular fungus) and also seen in some bacteria. Yeast cells release enzymes called zymase complex which bring about the fermentation. The reactions are similar to anaerobic respiration.

(2) Lactic acid fermentation : The type of fermentation in which lactic acid is the end product.

It is carried out by some bacteria (e.g. lactic acid bacteria), and also by animals (muscle glycolysis in animals, under oxygen deficiency, results in the formation of lactic acid this is whay we experience in muscle cramps, or "Charley horse").
