A semi-permeable membrane is a membrane which allows cells to pass through it. The cells which make up the membrane of the inside of the cheek of the human mouth, for example, are semi-permeable. This allows things, like nicotine for example, to be absorbed through the membrane walls while the walls maintain structural integrity.
a cell membrane is semi-permeable. meaning that it selectively chooses between what can go in and out of the cell. A door greeter is similar to this because a door greeter can tell who to allow in/out of the building they are in.
the concentration gradient will help to bring stuff into the cell and to move stuff out. Osmosis likes to move with the concentration gradient. Moving with a concentration gradient is passive transport and moving against it is active transport
No, rough endoplasmic reteculum is not related to cellular respiraton
who the knows
In Facilitated diffusion materials are transported across the plasma membrane without using up any energy. Plasma membranes is made up of phospholipid bilayers consisting of proteins which help in the transportation of larger materials.
The cell membrane is very much like the rubber part of an inflated balloon.
they're cousins
The same chemical reaction is occurring in both cellular respiration and decomposition. An organic compound such as glucose is used as fuel to run cellular respiration.
Because the end products of photosynthesis (glucose and oxygen) are the requirement to start cellular respiration.
Because the end products of photosynthesis (glucose and oxygen) are the requirement to start cellular respiration.
The products of the cellular respiration formula are the reactants of the photosynthesis formula, and the reactants of the cellular respiration formula are the products of the photosynthesis formula. Basically, they are opposite processes.
