<span>The commonly accepted values is 4 Calories per gram of protein and carbohydrate and 9 Calories per gram of fat. Since we have 2 grams of each, a little simple math will do: 2 g * 4 Cal/g + 2 g * 4 Cal/g + 2 g *9 Cal/g = 8 Cal + 8 Cal + 18 Cal = 34 Cal</span>

Predict what would happen if you treat cells with chemicals that block cytokinesis. Describe what you think the cells would look

Serjik [45]

Cell division is characterized by two important processes called the karyokinesis followed by the cytokinesis. Karyokinesis refers to the division of the nucleus which is followed by the division of the cytoplasm called the cytokinesis. In animal cells, it is by the formation of a cleavage furrow and in plant cells it is by the formation of a cell plate. Cytokinesis results in the formation of two daughter cells. If the cells are treated with chemicals that block cytokinesis, the seperation of cells is not possible leading to the formation of abnormally large sized cells, each containing two nuclei or sometimes can be multinucleated.

What is the main difference between aerobic respiration and anaerobic respiration?

garri49 [273]

The main difference between aerobic respiration and anaerobic respiration is that aerobic using oxygen in the reaction, while anaerobic does not.

Even though both aerobic and anaerobic respiration releases energy, but their reactants and other products are completely different.
For example in human, in aerobic respiration, oxygen and glucose reacts to give out carbon dioxide and water; while in anaerobic respiration, which usually happens during exercise when oxygen is not enough, the muscle cells uses only glucose to produce energy and lactic acid.

Therefore, the main difference is where aerobic uses oxygen, and anaerobic don’t.
