Mekanisme transpor melalui membran sel diantranya yaitu eksositosis dan endositosis. Bagaimanakan mekanisme transpor membran sel secara endositosi dan eksositosis?

Apa yang membedakan eksositosis dan endositosis? How do things move across the cell membrane, either in or out?

This animation shows two broad categories of how things pass into or out of a cell: Passive transport is dn no input of energy is required. For example, diffusion is a passive process in which particles move either into or out of the cell from an area of higher concentration to an area of lower concentration.

BIOLOGI SEL: PENDAHULUAN

Active transport, on the other hand, is when particles move from an area of lower concentration to an area of higher concentration. Because particles are moving against the concentration gradient, energy is required. After viewing this video, the viewer will be able to: Video is eksostosis animated explanation of Endocytosis and exocytosis.

Endocytosis is an energy-using process by which cells absorb molecules such as proteins by engulfing them.

Eksositosis dan Endositosis (Mekanisme transpor pada sel) by nt- end

It is used by all cells of the body because most substances important to them are large polar molecules that cannot pass through the hydrophobic plasma or cell membrane. The opposite process is exocytosis. Explore the types of passive and active cell transport with the Amoeba Sisters!

BIOLOGI SEL: PENDAHULUAN

Their nutritional requirements are obtained from minerals and endosiitosis for hydrogen from the soil. The whole process can be linked to a person transpiration pullpulling a bucket full of water stresses on the water column with a steel rope unbroken and continuous water column with a strong cohesive force.

Uptake of Mineral Ions: All minerals cannot be passively absorbed by the roots.

This is due to the following reasons: So, most minerals must enter the root by active absorption into the cytoplasm of epidermal cells. This needs energy in the form of ATP. The active uptake of ions is partly responsible for water potential gradient in roots and therefore for the uptake of water by osmosis.

Some ions also move into the epidermal cells passively. The endodermal cells may have transport proteins embedded in their plasma membrane. Transport of Mineral Ions: After the ions have reached xylem through active or passive uptake, both, eksositoxis further transport up the stem to all parts of the plant is through transpiration stream.

Mineral ions are remobilised from older senescing parts.

Older leaves export their mineral content to younger leaves. In decidous plants, minerals move the other parts before leaf fall.

Readily mobilised eksosigosis are Phosphorous, Sulphor, Nitrogen and Potassium. Elements that are structural components like Calcium are not remobilised. Small amounts of Phosphorous and Sulphur are carried as organic compounds. This cell biology lecture explains the protein secretion pathway from ER to golgi network.
