cells part 2 Flashcards
When molecules move from areas of higher concentration to lower concentration, it is called what?
Passive Transport
When molecules move from areas of low concentration to higher concentration, it is called what?
Active Transport
What is the difference between active and passive transport?
active transport requires energy
What is the difference between endocytosis and exocytosis?
Endocytosis brings molecules in and exdocytosis sends molecules out
Exocytosis
the process by which cells move materials from within the cell into the extracellular fluid.
Diffusion
the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration.
Osmosis
Osmosis is the movement of molecules from a high concentration to a lower concentration
Facilitated Diffusion
the movement of specific molecules across cell membranes through protein channels
diffusion
the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration.
Photosynthesis
the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Endocytosis
a process by which cells take in the maliculs
Prophase
nucleus disappears they look like a bunch of bobby pines that are spread out
Anaphase
chromosomes separate and they all make math alligators in the middle of the cell
Metaphase
chromosomes in the middle all the bobby pins are in the middle of the cell
Telophase
2 new nuclei there are two different cycles with half bobby pins
Fermentation
uses glucose and no oxygen to produce ATP and lactic acid (Ex. blue cheese,yogurt ,sore muscles)
Alcohol Fermentation
Uses glucose, no oxygen, and YEAST or bacteria to produce ATP, CO2, and ethanol (ex. bread, cake, muffins)
What is the difference between facilitated diffusion and diffusion?
In simple diffusion, the substance passes between the phospholipids; in facilitated diffusion there are a specialized membrane channels.
where does cellular respiration take place
mitochondria and cytoplasm
what is cellular respiration?
the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.
cellular respiration equation
oxygen and glucose into water and carbon dioxide.
alcoholic fermentation
glucose + enzymes = carbon dioxide + ethanol/lactic acid.
