BIOMOLECULES
This biomolecule is the main source of quick energy for cells.
What is a carbohydrate?
This term describes the small building blocks of larger molecules.
What are monomers?
These substances are changed during a chemical reaction.
What are reactants?
This term describes all chemical reactions in a cell.
What is metabolism?
These biological molecules act as catalysts in cells.
What are enzymes
This biomolecule is made of amino acids and can act as enzymes.
What is a protein?
A monomer like glucose is said to be called this.
What is a monosaccharide
Energy is always absorbed during this part of a chemical reaction.
What is breaking chemical bonds?
These pathways break down biomolecules and release energy.
What are catabolic pathways?
This is the minimum energy needed to start a reaction.
What is activation energy
This biomolecule stores genetic information in cells.
What are nucleic acids?
Amino acids bond together to form this polymer
What is a polypeptide
Energy is always released during this part of a chemical reaction.
What is forming chemical bonds?
These pathways build biomolecules and absorb energy
What are anabolic pathways?
This enzyme region binds to the substrate.
What is the active site?
This hydrophobic biomolecule stores long‑term energy.
What are lipids?
Nucleotides are the monomers of this biomolecule.
What are nucleic acids?
This type of reaction absorbs more energy than it releases.
What is an endothermic reaction?
This describes the relationship between reactions in a metabolic pathway.
What is that the product of one reaction becomes the reactant of the next?
These two conditions strongly affect enzyme activity.
What are temperature and pH?
This is what the acronym BARF stands for.
What is, Breaking (bonds) is Absorbing (energy), and Releasing (energy) is Forming (bonds)
Cells break polymers into monomers for this reason.
What is to release energy and reuse building blocks?
During metabolism, atoms are not destroyed but are _______.
What is rearranged?
This explains why cells must use both anabolic and catabolic pathways.
What is to release energy and build needed molecules?
Increasing this speeds reactions only if substrate is available.
What is enzyme concentration?
