Ch. 2 voc. #2
| Term | Definition |
|---|---|
| chloroplasts | membrane bound organelles that use light energy and make food & sugar called glucose from water and carbon dioxide in a process known as photosynthesis |
| golgibodies | it prepares proteins for their specific jobs or functions |
| vesicles | packages the proteins into tiny membrane bound bull-like structures |
| lyosomes | contain substances that help break down and recycle cellular components |
| vocuoles | organelle that stores food and water; waste matter |
| semipermeable | it allows only certain substances to enter or leave a cell |
| passive transport | a movement of substance through a cell membrane without using the cell's energy |
| diffusion | the movement of substance from area of higher concentration to area of lower concentration |
| osmosis | the diffusion of water molecules only through a membrane |
| facilitated diffusion | when molecules pass through a cell membrane using special proteins called transport proteins |
| active transport | the movement of substance through a cell membrane only by using cell's energy |
| endocytosis | process during which a cell takes in a substance by surrounding it with cell membrane |
| excoytosis | process during which a cell's vesicles release their content outside the cell |
| cellular respiration | a series of chemical reactions convert the energy in food molecules into a usable form of energy called ATP |
| glycolysis | a process by which glucose (a sugar) is broken down into smaller molecules |
| aerobic | requires oxygen |
| anaerobic | does not use oxygen |
| fermentation | a reaction that eukaryotic and prokaryotic cells can use to obtain energy from food when oxygen levels are low |
| lactic acid | one type of fermentation occurs when glucose is converted into ATP and waste product is this |
| photosynthesis | a series of chemical reactions that convert light energy, water, and CO2 into the food energy molecule glucose and give off oxygen |
| alcohol fermentation | some types of bacteria and yeast make ATP through this process |
