What type of transport can move big molecules across the cellular membrane? What does the cell membrane keep out? When molecules use facilitated diffusion, what kind of protein will they need to help them move molecules across the membrane? What is the hydrophobic part of the cell membr...
•Endoplasmic reticulum (ER):A sort of membranous "highway" continuous with the nucleus and extending into the cytoplasm, and sometimes to the cell membrane.Smooth ERdoes not have ribosomes attached;rough ERdoes, giving it both its "studded" appearance and its name. Smooth ER synthesizes lipid...
Intracellular Transportation Cells are complex structures with many "moving parts" that need to get from one point to another within the cell in order to accomplish metabolic processes. There are specialized organelles in both plant and animal cells that make up the superhighways of a cell. ...
The functions of actin and its motor proteins myosins in the cytoplasm have been the subject of research for more than 100 years, but the existence and fun
It is selectively permeable, which means only select ions and molecules can pass through it by transport. Membrane transport can be actively or passively moving a substance from side of the membrane to another (Hardin, 2012). Passive transport does not require energy to move molecules across the...
Implantation occurs from the seventh day after ovulation and may last a few days. Between 7 – 10 days after ovulation implantation, bleeding may occur. This bleeding can be confused with menstruation but it has different characteristics such as a duration of a few hours to two days, a reddis...
The rough endoplasmic reticulum is situated closest to the nucleus—in fact, it’s attached to thenuclear envelope—so that molecules can move directly between the membranes. The ribosomes that are attached to the walls of the rough endoplasmic reticulum function just likefree ribosomeswould.That ...
What is a membrane that allows only certain things to pass through called? What is the plasma membrane and its structure? Fill in the blank. Diffusion across a biological membrane is called ___. During osmosis, which molecules move and through which type of membrane? What type of...
What is osmosis as used in biology to explain the semi-permeability of the membrane? What is the structure of the plasma membrane? What molecules can diffuse through the plasma membrane? What is the diffusion of water through a selectively permeable membrane called? a. facilitated diffusion b....
