| Question | Answer |
|---|---|
| This is the energy needed by a system to initiate a process. | Activation Energy |
| This is a specific region of an enzyme where a substrate binds and the chemical reaction occurs. | Active Site |
| Process requiring energy for the movement of particles across a cell membrane against the concentration gradient. | Active Transport |
| This bonds to thymine (T) in DNA. | Adenine |
| This is a molecule that contains both amino and carboxylic acid functional groups. They are the building blocks of protein. | Amino Acids |
| This is the main energy storage and transfer molecule in the cell. | ATP |
| This is a compound made up of carbon, hydrogen, and oxygen atoms; it is used by cells to store and release energy. Sugars are made by chloroplasts through photosynthesis and consumed by mitochondria through cell respiration. | Carbohydrate |
| This is the structural and functional unit of all living organisms, and are sometimes called the "building blocks of life." | Cell |
| A thin, flexible, semipermeable barrier around the cell which regulates what enters and leaves the cell. | Cell Membrane |
| This structure provides support and protection for plant cells. | Cell Wall |
| This is a plastid with chlorophyll in plants that photosynthesize. | Chloroplast |
| This is the unequal distribution of ions across a cell membrane. | Concentration Gradient |
| This bonds to guanine (G) in DNA. | Cytosine |
| This is a change in the structure of a protein due to changes in the environment, like temperature or pH. | Denature |
| The process when molecules tend to move from an area of high concentration to an area of low concentration. | Diffusion |
| This holds an organisms hereditary information. | DNA |
| This is the process where cells engulf material from outside their cell membranes. | Endocytosis |
| This is a membrane-bound organelle in eukaryotic cells that is the production and processing center of proteins and some lipids. | Endoplasmic Reticulum |
| These are complex proteins that speed up chemical reactions by lowering the amount of energy needed to get the reaction started. | Enzyme |
| These are cells where the genetic material is contained in membrane-bound nuclei. | Eukaryote |
| This is the transport of material out of a cell by means of a sac or vesicle that first engulfs the material and then is extruded through an opening in the cell membrane. | Exocytosis |
| This is also known as facilitated diffusion, a process by which substances are transported across cell membranes by means of protein carrier molecules. | Facilitated Transport |
| This organelle serves to process and package lipids and proteins in the cell. | Golgi Body |
| This bonds to cytosine (C) in DNA. | Guanine |
| This is a regulation of the internal environment of an organism. | Homeostasis |
| This is a modification of the lock and key model that suggests the active site of an enzyme is continually reshaped by interactions with the substrate until the substrate is completely bound and the chemical reaction occurs. | Induced Fit |
| A macromolecule made up of mainly carbon and hydrogen atoms that is primarily used for energy storage and in cell membranes. | Lipid |
| This is one explanation of enzyme specificity that states an enzyme and its substrate possess specific complementary geometric shapes that fit exactly into one another. | Lock And Key |
| This is a type of protein found in the cell membrane, which regulates the coming and going of substances into or out of the cell. | Membrane Protein |
| This is a macromolecule that holds cell information in a coded form. Made of sugar, phosphate and nitrogen-containing bases. | Nucleic Acid |
| This is the repeating structural unit that forms RNA and DNA. | Nucleotide |
| The structure that houses the cells genetic information. | Nucleus |
| The movement of water through a selectively permeable membrane from an area of high concentration to low concentration. | Osmosis |
| A non-energy requiring process that moves materials across a cell membrane with the concentration gradient. | Passive Transport |
| This is the substance(s) formed in a chemical reaction. | Product |
| These are organisms where the genetic material is not bound by a nucleus. They are usually unicellular. | Prokaryote |
| A macromolecule that contains carbon, hydrogen, oxygen, and nitrogen, which is used by the body for growth and repair. | Protein |
| In multicellular organisms, this is a function of mitosis along with growth and development. | Repair |
| This organelle synthesizes proteins. | Ribosome |
| This is an ability of a plasma membrane to allow some substances to cross across the membrane more easily than others. | Selective Permeability |
| This is an active transport mechanism by which cells pump sodium and potassium ions against the concentration gradient. | Sodium Potassium Pump |
| This is the material or substance on which an enzyme acts. | Substrates |
| This bonds to adenine (A) in DNA. | Thymine |
| This is a tiny fluid-filled cavity in the cytoplasm. It can be used for storage of biochemicals. | Vacuole |
