incorrect things to go over Flashcards
give 2 functions of the plasma membranes
regulates the movements of substances
receptors allow it to respond to chemicals
what organelle has a matrix and what does it contain
mitochondria
contains enzymes used in aerobic respiration
give 2 functions of the golgi apparatus
process and package lipids and proteins
makes lysosomes
give 2 similarities between the cilia and the flagella
both are structures that stick out of the surface of some cells
both have an outer membrane
give 2 differences between the cilia and flagella
flagella is longer than cilia
cilia are used to move substances along the cell surface, flagella are used to propell forward

where does facilitated diffusion occur
channel proteins
what is facilitated diffusion
when molecules diffuse through via a channel or carrier protein
what do channel proteins transport
transport polar molecules, charged and water soluble
what do carrier proteins transport
anything with the use of ATP
what is endocytosis
when a cell engulfs a substance into its surroundings, which is resulted by the cell membrane folding on itself
