1. the substances formed as a result of a chemical reaction or process, appearing on the right-hand side of a chemical equation
5. the basic unit of a chemical element
10. Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes
13. a protein that acts as a biological catalyst accelerating chemical reactions within living organisms without being consumed or altered in the process
14. a structure composed of different tissues that work together to perform a specific function
15. a substance upon which an enzyme acts or a surface or medium on which an organism grows or is attached
16. a group of atoms bonded together
18. a living individual encompassing any form of life such as a plant animal or microorganism
19. the minimum amount of energy required to initiate a chemical reaction or to convert reactants into a transition state
21. a membranes ability to allow some substances to pass through while preventing others acting as a gatekeeper for the cells environment

1. a type of lipid molecule that forms the primary structural component of cell membranes featuring a hydrophilic head phosphate group and two hydrophobic tails fatty acids
2. the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration
3. a group of organs that work together to perform one or more specific functions
4. a subcellular structure that has one or more specific jobs to perform in a cell
6. a group of similar cells that work together to perform a specific function
7. the specific region of an enzyme where substrate molecules bind and undergo a chemical reaction facilitating catalysis
8. a protein or nucleic acid losing its original shape and function often due to factors like heat chemicals or pH changes disrupting the bonds that hold the molecule together
9. the passive movement of water molecules across a semipermeable membrane from an area of lower solute concentration
11. substances that lack an affinity for water meaning they repel or are insoluble in water and are typically nonpolar
12. the movement of molecules from an area of high concentration to an area of low concentration
17. a substance or molecule that has a strong affinity for water meaning it readily dissolves in or mixes with water
20. the smallest structural and functional unit of an organism
