Cell Vocabulary Quiz – Part 2

Equilibrium

Answer When opposing forces are balanced out. Examples Same amount of + and – charges Same amount of sugar, salt or water inside and outside of a cell. Answer

Semipermeable

answer Partially permeable The cell membrane is semipermeable meaning that only certain things are let in and out of cells through their membrane. Only small and uncharged molecules can come through without a protein. answer

Concentration gradient

The direction or net movement of particles based on moving from high concentration to low concentration. Answer

Simple Diffusion

When small and nonpolar (Small and uncharged) molecules move through the cell membrane without the use of proteins. Answer

Facilitated Diffusion

Large and polar (large and charged) molecules move through proteins to get into or out of a cell. These always go with the concentration gradient meaning from high to low concentration. answer

Osmosis

Facilitated diffusion of water through the aquaporin's (protein). Answer

Active Transport

Answer Transport that uses energy (ATP) Active transport goes against the concentration gradient (low to high concentration) that is why the cell requires energy to do it. Answer

Homeostasis

The ability of the body to maintain a steady state despite changing conditions. Example Shiver vs . Sweat Answer

Photosynthesis

Changing CO2 and water into sugar and O2 Answer

Cellular Respiration

Changing sugar and O2 into CO2, H2O and Energy Answer

Fermentation

When O2 is not available for the process of cellular respiration organisms will convert sugar into alcohol or lactic acid. Answer

ATP

Answer Our bodies energy molecule. Created through the process of cellular respiration. Answer
