What is anabolism?

• the breakdown of larger molecules into smaller ones & releases energy
• the buildup of larger molecules from smaller ones & releases energy
• the breakdown of larger molecues & requires energy
• the buildup of larger molecules from smaller ones & requires energy

What is dehydration synthesis?

• catabolic process that joins small molecules by releasing water molecules
• anabolic process that joins small molecules by releasing a water molecules
• anabolic process that breaks apart larger molecules by absorbing water molecules
• catabolic process that breaks apart larger molecules by absorbing water molecules

What do cells use dehydration synthesis to do?

• to break apart amino acid molecules
• to join pyruvic acid molecules
• to join amino acid molecules
• to break apart citric acid molecules

What is a peptide bond?

• bond between a carbon atom of one amino acid & a nitrogen atom of another amino acid
• bond between an oxygen atom of one amino acid & a carbon atom of a water
• hydrogen bond between the hydrogen atoms of two amino acids
• covalents bond between the nitrogen atoms of two amino acids

What is hydrolysis?

• an anabolism reaction which decomposes carbohydrates, lipids, & proteins, and splits a water molecule in the process
• a catabolism reaction which decomposes carbohydrates, lipids, & proteins, and splits a water molecule in the process
• an anabolism reaction which builds up carbohydrates, lipids, & proteins, and splits a water molecule in the process
• a catabolism reaction which builds up carbohydrates, lipids, & proteins, and splits a water molecule in the process

What are enzymes?

• simple molecules that are almost always carbons that promote chemical reactions by adding energy
• complex molecules that are usually carbohydrates that increase the amount of energy required for a reaction to take place
• simple molecules that are mostly hydrogen ions that expend more energy during chemical reactions
• complex molecules that are almost always proteins that promote chemical reactions within cells by lowering the amount of energy required to start reactions

What do enzymes do?

• they speed the rates of metabolic reactions
• they slow down the rates of metabolic reactions
• they speed up the rates of catabolic reactions
• they slow down the rates of anabolic reactions

What is catalysis?

• the speeding up of a anabolic reaction via a catalytic enzyme
• the slowing down of a catalytic reaction via an anabolic enzyme
• the acceleration of a chemical reaction by a catalyst enzyme
• the deceleration of a chemical reaction by a catalyst enzyme
