Consider the biochemical pathway: A + E1 –> B + E2 –> C (Note that A, B, and C are molecules in the pathway, E1 is enzyme

MAVERICK [17]

Answer:

The compound that will accumulate is B.

Explanation:

Enzymes in any biochemical process are the protein molecules that speed up the rate of the biological reaction. It lowers down the activation energy of the reactant molecules.

Since from the question:

A + E1 –> B + E2 –> C

Given that A, B and C are the molecules in the pathway and E1 and E2 are the enzymes.

This means that A undergoes some biological reaction in which E1 is acting a catalyst to give B and which further undergoing another biological reaction to give C in the presence of enzyme E2.

Since, E2 is inactive,

A will form B but B will not be able to undergo further reaction and thus, C can not be formed.

Thus A is consumed and C is not formed. The compound that will accumulate is B.

In an electron dot diagram of propane (C3H8), how many double bonds are present?

NeX [460]

Answer:- none

Explanations:- For naming hydrocarbons we use the suffix -ane, -ene and -yne.

-ane is used when we have only single bonds between all carbons. -ene is used if there is any double bond between two carbons and the -yne is used if there is any triple bond between two carbons.

The given name of the compound is propane. It ends at -ane and so it's an alkane and must have single bonds between all the carbons it has. So, there are zero double bonds present in $C_3H_8$ .
