Chapters 2 - 6

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What does it mean if a reaction is exothermic?

Back

An exothermic reaction is one that releases energy to the environment.

Front

What is the 'R' Group in amino acids?

Back

The 'R' Group is the variable side chain that determines the specific properties of each amino acid.

Front

What is hydrolysis?

Back

Hydrolysis is the process used to split polymers by adding water.

Front

Which structural level of a protein is least affected by hydrogen bonds?

Back

The primary level of a protein structure is least affected by hydrogen bonds.

Front

Define selectively permeable membrane.

Back

A selectively permeable membrane allows certain molecules to pass through while blocking others.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes lower the activation energy required for a reaction to occur, speeding up the process.

Front

What is the difference between dehydration synthesis and hydrolysis?

Back

Dehydration synthesis joins molecules by removing water, while hydrolysis splits molecules by adding water.

Front

What is the significance of the primary structure of a protein?

Back

The primary structure determines the unique sequence of amino acids in a protein, which influences its function.

Front

What is the function of the carboxyl group in amino acids?

Back

The carboxyl group acts as an acid, donating a hydrogen ion (H+) in solution.
