Q. Due to the higher concentration of oxygen in the air than your blood, oxygen goes from the lungs into the red blood cells by. Facilitated Diffusion. Simple Diffusion. Active Transport. Q. This cell structure helps organisms maintain homeostasis by controlling what substances may enter or leave cells. Q. Passive transport requires no.
Active transport is a method of cell transport that requires energy. Energy is expended because the cell has to move materials from an area of low concentration to an area of high concentration. Imagine you have 5 large marshmallows in your mouth. Adding another marshmallow would be like a cell trying to complete an active transport.

Give a scenario where a cell may need to perform a form of endocytosis. While water molecules are polar, they are also very small. Cells lining the gut need to take in glucose, but at a certain time, the concentration of extracellular glucose is lower than the concentration already stored in the cells.
These high school biology homework pages are full of pictures, diagrams, and deeper questions covering diffusion, facilitated diffusion, active transport, endocytosis, and more. This unit is part of my High School Biology for the Whole Year Bundle.

Now hypotonic, hypertonic, and isotonic solutions usually deal with cellular osmosis which diffuses over a selectively permeable membrane. Osmosis is the movement of water and tends to diffuse by moving the water from areas of higher concentrations to areas of lower concentrations. Lastly, a selectively permeable membrane can restrict what.
National 5 Biology 1.2 Transport Across Cell Membranes Homework 11) The apparatus shown below was used to investigate the movement of water into and out of a model cell. The model cell had a selectively permeable membrane. The liquid level in the glass tubing was measured every 10 minutes for 60 minutes. The results are shown in the table below.
