The answer is: A. True
Complex sugars or polysaccharides are composed of basic units called monosaccharides that are linked via glycosidic bonds. Glycosidic bond is formed through condensation reactions (water is released) that occur between a hydroxyl (OH) oxygen atom on one sugar and the α-anomeric form of C-1 on the other. There are are two types of glycosidic bonds:
- 1,4 alpha ( the OH is below the glucose ring)
- 1,4 beta glycosidic bonds (the OH is above the glucose ring)
Amylase is an enzyme that breaks down starch into smaller glucose molecules, it act on α-1,4-glycosidic bonds and it works in mouth where the digestion begins (salivary amylase) . Maltase breaks down maltose into glucose; sucrase, breaks down sucrose into glucose and fructose; and lactase, which breaks down lactose into glucose and galactose work in small intestine and also act on α-1,4-glycosidic bonds.
Answer:
D
Explanation:
The phosphofructokinase-1 reaction is endergonic.
Answer:
OB) An elephant in the savannah develops without the ability to hear. A salamander living in a cave is born without, eyesight or fully developed eyes.
Explanation:
Adaptations are gradual modifications and changes in the physical characteristics or behavior of an organism, so that it could facilitate the survival of the organism in that particular environment.
In case of elephant without ability to hear specially in the regions of Savannah where there is vast grasslands with scanty vegetation and animals, then the elephant can't hear any sound of danger like approaching calamities, also it could hear the call of other elephants, in case if the elephant becomes segregated.
In salamander, low eyesight or low vision will further add to the misery, as there is already darkness in the cave. It could fall prey to any predator or it could not be able to feed on consumable organisms as it could see properly.
Ionic bonds <span>are the type of bonds where there is </span>transfer<span> of electrons from one atom to another. The electrons are removed and from one atom and attached to another. A good example is salt which is composed of sodium and chlorine. Sodium readily loses one of its electrons and chlorine readily accepts it. Before losing the electron, sodium has a positive charge, but then becomes negatively charged after giving up the electron. Chlorine has a positive charge before gaining the electron but becomes negatively charged after gaining the electron. These opposite charges between sodium and chlorine attract the two elements together to form the ionic bond.</span>
<em>The ATP molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. In this form, energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.</em>
