Answer:
i believe it is the middle one. "Gold" is a part of the metal group 11
<span>Cell membrane protects, regulates and controls the movement of object that goes in and out of the cell.
Cell membrane is comprised of phospholipids (its major component ) which can create lipid bilayers because of their water attracting characteristics. Another lipid inside the cell membrane is </span>cholesterol, <span>which makes the cell membrane more fluid. Cholesterol is a waxy fat-like substance found in all cells of the body. </span>
<span>When you have a high cholesterol, it can create a plaque in your arteries thus, develop a high risk of heart disease. People who have high cholesterol has a greater possibility to acquire coronary heart diseases.</span>
The answer to this question is a mean of 6.5 hours.
<span>Cardiac arrest is a situation when the heart loss its
function of pumping blood in the body. The main cause of cardiac arrest is due
to coronary artery disease. Some of the causes of cardiac arrest are heart
failure, lack of oxygen in the body, and due to a plenty of blood loss. If a
person is under cardiac arrest and not treated immediately, the patient will
die. </span><span> </span><span> </span><span> </span>
Answer:
The given characteristics can be shown by Enzymes.
Explanation:
- Enzymes are substances, mostly proteins, that helps in increasing the speed or rate of a biochemical reaction (conversion of substrate to product) by reducing the activation energy barrier of the reaction.
- The enzymes which are made up of proteins have an specific location or region inside them which is called the Active Site.
- The biochemical reaction occurs at this active site.
- The specific substrate molecule(s) comes and associated with the active site of the enzyme, mostly by means of non-covalent interactions.
- By means of amino acid side chains (which have a definite pKa) the exact environment (oxidising or reducing) required for the chemical reaction to occur is maintained by the enzyme at its active site.
- After associating with its substrate(s) the enzyme undergoes certain conformational changes in order to position the substrate(s) in the correct orientation such the biochemical reaction can occur.
- After the products are formed, the enzyme further undergoes some conformational changes to release them.
- Enzymes are similar to transport proteins because:
- When the concentration of substrates is far more than that of the available enzymes molecules, then the enzymes would get saturated with substrates, like the transport proteins.
- The enzymes are highly specific for their substrates like the transport proteins.
- The enzymes undergo conformational changes during the biochemical reaction like the transport proteins.
- Both the rate of enzymatic reaction and membrane transport is regulated by the cell.
Explanation:
A TVET qualification is easier to achieve and at a lower price also focused on getting you into the workforce faster. University is geared towards the transfer of knowledge rather than skills.
the stigma associated with TVET colleges are that those who go to the college is a failure. or a institute for those who aren't smart enough. And also for those who failed to get into university
