Vitamin c is soluble in water and vitamin d is lipid soluble. how does the structure of the cell membrane determine the route taken by each vitamin?
Vitamin C is water soluable so the only way it can be transported is by faciliated difficusion using a channel protein. Channel proteins allow polar, watersoluable substances and ions to pass across the cell membrane using faciliated diffusion. Vitamin D is lipid soluble therefore it can pass through using simple diffusion because the phospholipid bilayer lets it pass through down its concentration gradient.
What is membrane infolding?
Membrane infolding is a process in which the cell membrane folds in on itself, creating internal compartments or structures within the cell. This folding increases the surface area of the membrane, allowing for more efficient transport of molecules and signaling within the cell. It is a common phenomenon in cells to increase membrane surface area for various functions such as nutrient uptake or organelle formation.
What structure is involved in phagocytosis?
Plasma Membrane !
What is the process by which materials are engulfed by the cell membrane and brought into the cell?
The process by which materials are engulfed by the cell membrane and brought into the cell is called endocytosis. It involves the formation of vesicles that surround the material to be taken in and then fuse with the cell membrane to release the contents into the cell. There are two main types of endocytosis: phagocytosis, for larger solid particles, and pinocytosis, for smaller liquid particles.
What Controls what moves in and out of the cell?
Cell membrane
What is folic good for?
Folic acid (also called vitamin B9) promotes white and red blood cell formation, cell maintenance and repair, synthesis of DNA. It has also been shown to remove homocysteine from the blood. High levels of homocysteine in the blood have been shown to be one of the many factors that can cause heart disease.Folic is vitamin B which is essential for reproduction and cell growth.
What is the vesicular formation membrane bound sac called?
These are called vesicles and they transport various substance into the cell and out of the cell.
What does vitamin A do in the cell?
Vitamin A is necessary for normal cell growth and development. Although the mechanisms by which vitamin A promotes cell growth and development are not yet fully understood, it is known that retinoic acid is necessary for the synthesis of many glycoproteins, which control cellular adhesion (the ability of cells to attach to one another), cell growth and cell differentiation.
What is one result of this complement fixation is which appears in the membrane of the foreign cell?
One result of complement fixation is the formation of the membrane attack complex (MAC) on the surface of the foreign cell. The MAC creates pores in the cell membrane, leading to cell lysis and ultimately cell death.
Movement of large molecules by formation of a vesicle?
This process is called endocytosis. It involves the ingestion of large molecules or particles by the cell through the formation of a vesicle. The vesicle is formed when the cell membrane engulfs the material to be transported, creating a membrane-bound sac within the cell.
What extra embryonic membrane is the first site for red blood cell formation?
The yolk sac
What is the process of taking substances into a cell by surrounding it with the cell membrane called?
The process of taking in substances into a cell by surrounding them with the cell membrane is called endocytosis. It involves the formation of vesicles that engulf and transport the substances into the cell. Endocytosis is essential for nutrient uptake and cellular communication.

During cytokinesis in plant cells the new cell membrane forms before the new cell wall does?
Yes, during cytokinesis in plant cells, a cell plate forms between the two daughter cells, which eventually becomes the new cell wall. The cell plate is made up of vesicles carrying cell wall material that fuse together to form a continuous wall dividing the two daughter cells. The cell membrane surrounds each daughter cell before the cell plate completes its formation.

How does kinetic energy weaken the cell membrane?
Kinetic energy can weaken the cell membrane by causing disruptive vibrations that can break down the lipid bilayer structure. These vibrations can lead to the formation of holes or disruptions in the membrane, compromising its integrity and allowing substances to leak in or out of the cell.
What is vitamin b12 good for?
Vitamin B-12 is necessary for the proper formation of red blood cells and transport of oxygen through the body. It is also necessary for neurological health as it forms a necessary component of nerve cell axonal sheathes (myelin).
