Ch. 2 voc. #2

TermDefinition
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
