An increase in the ratio of insulin to glucagon will increase the activity of which of the following enzymes (+ indicates activi
AleksAgata [21]

Answer: An increase in the ratio of insulin to glucagon will increase the activity of --

- Acetyl-CoA carboxylase(+)

-Phosphofructokinase PFK2(+)

-Glycogen synthase(+)

- Hormone sensitive lipase (-). The hormone sensitive lipase activity is not increased with increased insulin activity.

Explanation: increased insulin - glucagon ratio is usually high in fed state.Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.

The formula of nitrobenzene is c6h5no2. the molecular weight of this compound is __________ amu.
mafiozo [28]

The molecular weight of a given compound would simply the sum of the molar weights of each component.

 

The molar masses of the elements are:

C = 12 amu

H = 1 amu

N = 14 amu

O = 16 amu

where 1 amu = 1 g / mol

 

Since there are 6 C, 5 H, 1 N and 2 O, therefore the total molecular weight is:

molecular weight = 6 (12 amu) + 5 (1 amu) + 1 (14 amu) + 2 (16 amu)

molecular weight = 123 amu

 

Therefore the molecular weight of nitrobenzene is 123 amu or which is exactly equivalent to 123 g / mol.

What can you infer about aspirin’s ester group?
Reil [10]

Answer:

Option B, aspirin’s ester group provides greater digestibility to aspirin

Explanation:

Aspirin ester group has three parts

  1. carboxylic acid functional group (R-COOH)
  2. ester functional group (R-O-CO-R')
  3. aromatic group (benzene ring)

Aspirin is a weak acid and hence it cannot dissolve in water readily. The reaction of Aspirin ester group with water is as follows -

aspirin

(acetylsalicylic acid) + water → salicylic acid + acetic acid

(ethanoic acid)

Aspirin passes through the stomach and remains unchanged until it reaches the intestine where it hydrolyses ester to form the active compound.
