What is the effect of adding more substrate in a substrate-limited reaction?

Back

It increases the rate of reaction by providing more reactants for the enzyme to act upon.

Front

What distinguishes deoxyribose from ribose?

Back

Deoxyribose lacks an oxygen atom at carbon 2, making it different from ribose.

Front

What type of bond connects nucleotide residues in a nucleic acid?

Back

Phosphodiester bond connects nucleotide residues, forming the backbone of nucleic acids.

Front

Which coenzyme is important for carrying and transferring electrons?

Back

NADH is a key coenzyme that carries and transfers electrons in metabolic reactions.

Front

Which end of a nucleic acid chain has a phosphate group at its terminal?

Back

The 5' end of a nucleic acid chain has a phosphate group at its terminal.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up biochemical reactions without being consumed.

Front

Define substrate in the context of enzyme activity.

Back

A substrate is a molecule upon which an enzyme acts to facilitate a chemical reaction.

Front

What is the significance of the 3' and 5' ends in nucleic acids?

Back

The 3' and 5' ends indicate the directionality of the nucleic acid strand, crucial for replication and transcription.

Front

Explain the concept of enzyme saturation.

Back

Enzyme saturation occurs when all active sites of an enzyme are occupied by substrates, leading to a maximum reaction rate.

Front

What is the function of coenzymes in enzymatic reactions?

Back

Coenzymes assist enzymes by providing necessary functional groups or transferring electrons.
