Sucrase breaks down sucrose (or “table sugar”) into glucose and fructose, and lactase breaks down lactose (or “milk sugar”) into glucose and galactose. The monosaccharides (glucose) thus produced are absorbed and then can be used in metabolic pathways to harness energy.

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.

Chargaff's Rule. If there is 20% Adenine in the cell, what is the percentage of Thymine, Guanine, and Cytosine found in the same
Ulleksa [173]

Answer:

A= 20%

G= 30%

T= 20%

C= 30%

Explanation:

Recall that the sum of all nitrogenous bases in the DNA nucleotide is equal to 100%. And specific base pairings of Adenine to Thymine (A=T), and Cytosine to Guanine (C=G) must be equal.

So, the percentage of Adenine equal thymine, and that of cytosine equals guanine.

Now, A + T + C + G = 100%

So, if Adenine makes up 20% of the DNA nucleotides, Thymine is also 20%.

Then, 20% + 20% + C + G = 100%

40% + C + G = 100%

C + G = 100% - 40% = 60%

So, divide 60% by 2 to obtain the individual percentage of cytosine and guanine. Each will take 30%

Finally, A= 20%; G= 30%; T= 20%; C= 30%

How does a pond form?
ollegr [7]

Hello There!

-There are 2 possible ways that a pond could form-

The first way it could happen is because of erosion. Erosion is the movement of weathered materials. This includes gravel, soil, and sand. This is the reason why the Earth's surface is always changing.

The second way ponds could made is by a person. This is called man made because someone had to be able to build hem
