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.

In order to improve fat digestion, large fat globules must first be dispersed into smaller droplets in a process called ________
Ludmilka [50]

In order to improve fat digestion, large fat globules must first be dispersed into smaller droplets in a process called <u>emulsification.</u>

<h3 /><h3>What is emulsification in the digestive system?</h3>

Fat emulsification is the process of increasing the surface area of fats in the small intestine by grouping them into small clusters. Large lipid globules are split up into a number of smaller lipid globules. In the chyme, these tiny globules are widely dispersed rather than aggregating into larger groups. Hydrophobic compounds include lipids. Bile salts, are present in bile and have both hydrophilic and hydrophobic sides.

Due to the fact that lipases can only effectively act on lipids when they are broken down into small aggregates, emulsification is crucial for the digestion of lipids. The lipids are converted into fatty acids and glycerides by lipases.

Trauma to the spinal cord is always serious. The higher it occurs in the spine, the more serious it is. Why should this be so
svet-max [94.6K]

Answer:

As you get higher up the spinal chord it branches out further into more nerves branching off into the body. These nerves will be affected negatively. The further up the injury, the more nerves are damaged. It is also getting closer to the brain stem so there is a higher chance of widespread paralysis.
