What is the oxidizing agent in the following reaction?
Andru [333]

Answer:

The answer is d. pyruvate

Explanation:

An oxidizing agent is the substance that gains electrons in a chemical reaction. At the end of the reaction it is reduced and its oxidation state increased.

A reducing agent is the substance that loses electrons in a chemical reaction. At the end of the reaction it is oxidized and its oxidation state decreased.

Pyruvate gains one electron, it is reduced from pyruvate to lactate; thus, pyruvate is the oxidizing agent.

NADH loses one electron, it is oxidized from NADH to NAD; thus, NADH is the reducing agent

For each region of the lac operon on the F' plasmid, I+ P+ Oc Z− Y+ , determine whether the region is wild type (that is, it pro
UNO [17]

Answer:

A,B and E

Explanation:

  • I+: I refers to the lac repressor, the + indicates that the repressor is functional
  • P+:  P refers to the promoter region and the + indicates that the promoter is functional
  • Oc:  O refers to the operator region, but the Oc indicates that the operator is constitutive ie. that it is always on/ can't be turned off.
  • Z-: Z refers to the LacZ gene which produces β-galactosidase. Z- indicates that this gene is non-functional
  • Y+:  Y refers to the LacY gene which produces the permease protein. Y+ indicates that this gene is functional

So based on the breakdown above:

  • A is true because P+.
  • B is true because I+.
  • C is not true because the lac operon is an inducible system. The operator needs to be able to be repressed. In this case the operator is constitutive (always on)  which is not the correct form.
  • D is not true because Z-, no β-galactosidase is produced.
  • E is true because Y+.

Only A, B and E apply.
