a) Pyruvate is a three-carbon molecule, so two molecules can be produced from each molecule of glucose. In total, from 4 molecules of glucose that enter glycolysis, there will be produced eight molecules of pyruvate.

b) PA becomes Lactic Acid instead of Acetyl CoA in anaerobic respiration (that is in auscense of oxygen), particularly when the cell carries out lactic acid fermentation, which is what can happen in the mitochondria of muscle cells when faced with a very demanding stimulus.

<span> One reason farmers often choose GM crops over non-GM crops is because GM crops are able to produce more yield. When farmers use GM crops, there are many benefits that they could gain. It has been proven that GM crops are more resistant to pests, and other harmful substances, which also reduce the costs for pesticides and crop-maintenance. Since GM crops are more resistant to harmful substances, more of them can be used by farmers.</span>
