Biochemistry

Front

What are enzymes?

Back

Enzymes are biological catalysts that speed up chemical reactions in living organisms.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

Front

What type of molecule is water?

Back

Water is a polar molecule, meaning it has a partial positive charge on one side and a partial negative charge on the other.

Front

What is the relationship between monomers and polymers?

Back

Monomers are the building blocks of polymers; they are small molecules that join together to form larger structures.

Front

What is the wrong polymer/monomer pair?

Back

Lipids: monosaccharides is incorrect; lipids are made of fatty acids and glycerol, not monosaccharides.

Front

What happens to heat when water evaporates?

Back

Water absorbs heat when it evaporates, which helps cool the surrounding environment.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes lower the activation energy required for a reaction, thus speeding up the reaction.

Front

How do temperature and pH affect enzymes?

Back

Enzymes are sensitive to temperature and pH; extreme conditions can denature them, affecting their function.

Front

What is metabolism?

Back

Metabolism is the sum of all chemical reactions that occur within a living organism to maintain life.

Front

What are nucleic acids made of?

Back

Nucleic acids are made of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base.
