Allosteric Inhibition Definition

Allosteric Inhibition Definition Allosteric inhibition is the slowing down of enzyme-catalyzed chemical reactions that take place in cells. These metabolic processes are responsible for the proper functioning and maintenance of balance in our body, and allosteric inhibition can help regulate these processes. Essentially, metabolic processes break down and important molecules are formed. They are essential … Read more

Selective Permeability Definition, &Function

Selective Permeability Definition Selective permeability is a property of cell membranes that only allows certain molecules to enter or leave the cell. This is important for the cell to maintain its internal order regardless of changes in the environment. For example, depending on metabolic activity, water, ions, glucose, and carbon dioxide must be imported or … Read more

Rough Endoplasmic Reticulum

Rough Endoplasmic Reticulum The rough endoplasmic reticulum (ER rough) is part of the cell’s endomembrane system and a subset of the endoplasmic reticulum (ER). This organelle is mainly concerned with the synthesis, folding, and modification of proteins, especially those that have to be delivered to different organelles within the cell or secreted by the cell. … Read more

It is common knowledge that years ago the windshields were … Read more

What is exocytosis? Exocytosis mechanism

What is exocytosis? As compared to endocytosis, exocytosis is a process that is used to use energy to move materials from inside the cell to the outside of the cell. Therefore, it is a kind of active transport mechanism and the opposite of endocytosis. Generally, in this exocytosis mechanism, a special vesicle attached to the cell … Read more

Definition of Endocytosis, and Process of Endocytosis

Definition of Endocytosis  Endocytosis is a cellular mechanism by which a cell internalizes substances such as proteins, fluids, electrolytes, microorganisms, and certain macromolecules from its external environment. These substances are subjected to certain processes of decomposition into smaller elements, either for use by the cell or for elimination. White blood cells of the immune system … Read more

Spirogyra Definition, Classification, and Morphology of Spirogyra

Spirogyra Definition Spirogyra is a green alga that occurs mainly in fresh water in the form of lumps. These are also known as water silk or mermaid braids. It is a unicellular organism, but it can be seen in freshwater bodies when it agglomerates into a multicellular structure. Spirogyra is composed of chlorophyll, which gives it … Read more
