Answer:
The phosphate group is negatively charged polar head , which is hydrophilic . the fatty acids chains are the uncharged, nonpolar tails , which are hydrophilic
Answer:
Sucrose passes through your mouth and stomach virtually undigested. Once it enters the initial part of your small intestine, an enzyme called sucrase is secreted from the mucosal membrane. Sucrase breaks down sucrose by cleaving it in half, which produces one molecule of glucose and one molecule of fructose. The glucose is immediately absorbed into the bloodstream and transported around the body. In contrast, fructose is also absorbed in the small intestine, but it’s shuttled to the liver where it spends more time either being reduced into glucose, stored as glycogen or converted into lipids. In addition to sucrase, another enzyme called isomaltose glycoside hydrolase can also help facilitate the breakdown of sucrose. Overall, sucrose is readily assimilated and produces a quick boost of energy -- about 3.94 kilocalories of energy per gram.
<span>This is a true statement, to an extent. It is also determined by food intake, environment, age, and stress inhibition activities. Undertaking activities such as smoking and drinking can also predispose a person to holding more visceral fat than people who do not smoke or drink.</span>
The electron transport chain is located on the inner membrane of the mitochondria, as shown below. The electron transport chain contains a number of electron carriers. These carriers take the electrons from NADH and FADH2, pass them down the chain of complexes and electron carriers, and ultimately produce ATP.
The correct option is A.
When an end of a tuning fork that is vibrating is placed against a table, it produces a sounder that is dramatically louder than the original sound produced by the vibrating tuning fork. At this stage, the tuning fork is forcing the table to vibrate at its own frequency. Thus, the statement in option A is not true.
