QUESTION:

The oxidation of oxygen in peroxides is?

OPTIONS:

  • +1
  • -1
  • +2
  • -2

CORRECT OPTION:

-1

EXPLANATION:

Peroxides include hydrogen peroxide, H2O2. This is an electrically neutral compound and so the sum of the oxidation states of the hydrogen and oxygen must be zero.

REACTION KINETICS

QUESTION:

Some reaction start very slow, but then gain speed and eventually become very fast. These reactions exhibit which phenomena?

OPTIONS:

  • Catalyst activation
  • Catalyst poisoning
  • Inhibition
  • Auto catalysis

CORRECT OPTION:

Auto catalysis

EXPLANATION:

In these reaction product formed acts as a catalyst. That is why they start very slow, but then gain speed (as the product catalyst is available) and eventually become very fast.

DIGESTION

QUESTION:

Trypsinogin is converted into trypsin by the activity of:

OPTIONS:

  • Goblet cells
  • Absorbtive cells
  • Enteropeptidase
  • Enterokinase

CORRECT OPTION:

Enteropeptidase

EXPLANATION:

Trypsinogen is the precursor form of the pancreatic enzyme trypsin. It is found in pancreatic juice, along with amylase, lipase and chymotrypsinogen. It is activated by enteropeptidase, which is found in the intestinal mucosa, to form trypsin. Once activated, the trypsin can activate more trypsinogen into trypsin. Trypsin cleaves the peptide bond on the carboxyl side of basic amino acids such as arginine and lysine.
