Answer:
A. pH
Explanation:
Denaturation of proteins is a protein whereby the protein molecule loses its primary structure and ultimately its physical functioning as a result of factors including pH, temperature or concentration of chemicals. Based on this definition, it is visible that denaturation of proteins can be caused by these three factors: pH, chemical and temperature.
However, in this case of PEPSIN enzyme, which is a proteinous molecule produced in the stomach of humans and functions in breaking down proteins, its denaturation occurs as it moves along the digestive tract to the intestines. This is as a result of the changes in pH in the digestive tract.
The pH of the stomach where pepsin is produced is acidic i.e. <3.0. However, as one moves towards the intestine, the pH increases, which is unfavorable or considered harsh for the pepsin enzyme. Hence, it gets denatured.
To increase the amount of food produced by corn crops, the farmer could select for more cobs on the corn.
How this flowers structure relates to its function is by the hight and the sizes of its leafs.
Answer:
True
Explanation:
A glucose molecule enters glycolysis in the cytoplasm of the cell. The glycolytic reactions break down one molecule of glucose into two molecules of pyruvate. Each of the pyruvate molecules is then decarboxylated and is oxidized into acetyl CoA. Acetyl CoA enters Kreb's cycle. Acetyl CoA is completely broken down into CO2 and H2O in Kreb's cycle. In this way, glycolysis and Kreb's cycle break down the glucose molecule into CO2 and H2O in a stepwise manner.
