Chapter 3 Vocab Flashcards
Energy requiring process on which transport proteins bind with particles and move them through a cell membrane.
Active Transport
Chemical reactions occur that break down food molecules into simpler substances and release their stored energy.
Cellular respiration
A type of passive transport in cells in which molecules move from areas where there there are fewer of them
Diffusion
Process by which a cell takes in a substance by surrounding it with the cell membrane
Endocytosis
A type of protein that regulates nearly all chemical reactions in cells
Enzyme
Occurs when molecules of one substance are spread evenly throughout another evenly
Equilibrium
Process by which vesicles release their contents outside the cell
Exocytosis
Process by which oxygen-lacking cells and some one called organisms release small amounts of energy from glucose molecules and produce wastes such as alcohol, carbon dioxide and lactic acids.
Fermentation
Compound such as H2O that is made from elements other than carbon and whose atoms usually can be arranged only in one structure
Inorganic Compounds
The total of all chemical reactions in an organism
Metabolism
A combination of substances in which the individual substances do not change or combine chemically but instead retain their own individual properties can be gases, solids, liquids or any combination of them
Mixture
Compounds that always contain hydrogen and carbohydrates, lipids, proteins and nucleic acids
Organic Compound
A type of passive transport that occurs when water diffuses through a cell membrane
Osmosis
Movement of substances through a cell membrane without the use of cellular energy includes diffusion, osmosis, and facilitated diffusion
Passive transport
Process by which plants and many other procedures use light energy to produce a simple sugar from carbon dioxide and water and give off oxygen
Photosynthesis
