What is an exergonic reaction?

Back

An exergonic reaction is a chemical reaction that releases energy to the surroundings.

Front

What characterizes a polar covalent bond?

Back

A polar covalent bond involves unequal sharing of electrons between atoms.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes lower the activation energy required for reactions to occur.

Front

What unites all life forms, including Bacteria, Archaea, and Eukarya?

Back

Common ancestry and evolution.

Front

What is required for mRNA to be fully processed before translation?

Back

mRNA needs a 5' cap and a poly A tail, and it must have introns removed.

Front

What is the definition of activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus, while eukaryotic cells do.

Front

What is a ribosome's function in a cell?

Back

Ribosomes synthesize proteins by translating mRNA.

Front

What is the significance of the 5' cap on mRNA?

Back

The 5' cap protects mRNA from degradation and helps in ribosome binding.

Front

What is the function of introns in mRNA?

Back

Introns are non-coding sequences that are removed during mRNA processing.
