What is the movement of materials through a cell membrane?
Movement of substances into and out of cells include passive mechanisms that do not require cellular energy (diffusion, facilitated diffusion, osmosis, and filtration) and active mechanisms that use cellular energy (active transport, endocytosis,and exocytosis).
Does not require light?
cellular respiration
Does Alltell require a contract for their cellular service?
Alltell does not require a contract for their cellular service. You can find more information about different cellular services at heir stores or online wedsites.
Describe methods by which substances enter and leave cells that do not require cellular energy?
Diffusion-movement of substances from a region of higher concentration to a region of lower concentration down a concentration gradient. Osmosis (also similar to diffusion) - movement of water molecules from a region of higher water potential to a region of lower water potential down a water potential gradient:)
Does bacteria require ATP for its cellular functions?
Yes, bacteria require ATP for their cellular functions. ATP is a molecule that provides energy for various cellular processes, including metabolism and growth, in bacteria.
Do plants require oxygen for cellular respiration?
yes they do
What is the cellular movement of a substance that does NOT require energy?
Passive transport
Does cellular division require energy?
yes, everythingrequires energy.
All cellular activities require what?
They all need to repodes
Why can't heat energy travel through space by conduction or convection?
Both of these methods require the presense of matter.Both of these methods require the presense of matter.Both of these methods require the presense of matter.Both of these methods require the presense of matter.
What does cellular resperation require?
oxygen, atp, releases carbon dioxide
What parts of cellular respiration don't require oxygen?
Glycolysis is the only part of cellular respiration that does not require oxygen. It is the process by which glucose is broken down to produce pyruvate and a small amount of ATP. The subsequent steps of cellular respiration, including the Krebs cycle and electron transport chain, require oxygen to fully extract energy from glucose.
