Describe the 4 combinations of active or inactive regulatory proteins that could be present at any time in the cell

Biology
1 answer:
Sergeeva-Olga [200]4 years ago
8 0

The bacterial genes are usually found in operons. Each operon comprises regulatory sequences of DNA that function as binding sites for regulatory proteins, which inhibit or encourage transcription. The regulatory proteins usually combine with small molecules that can make the protein inactive or active by altering its tendency to combine with DNA.  

The four combinations of active or inactive regulatory proteins, which could be observed at any time in the cell are:

1. Active repressor, active activator,

2. Active repressor, inactive activator

3. Inactive repressor, active activator

4. Inactive repressor, inactive activator

Rapid water movement between the extracellular fluid and the intracellular fluid is termed?
MatroZZZ [7]

Rapid water movement between the extracellular fluid and the intracellular fluid is termed as Fluid Shift

<h3>How does the fluid shift works and affect the body?</h3>

When bodily fluids transfer across the fluid compartments, fluid shifts happen. Hydrostatic pressure gradients and osmotic pressure gradients work together physiologically to cause this. Water will passively travel from one area to the next through a semipermeable barrier until the hydrostatic and osmotic pressure gradients are equal. Fluid changes can result from a variety of medical problems. Critical organs like the brain, heart, and kidneys are put at risk when fluid shifts out of the blood vessels (the intravascular compartment), the cells (the intracellular compartment), the interstitial space, the cells (the intracellular compartment), the intracellular space, the cells (the intracellular compartment), and the brain cells (the intracellular compartment). When fluid shifts into the brain cells, it can cause a stroke.

Give a scenario where a cell may need to perform a form of endocytosis and exocytosis
Firdavs [7]
<span>A scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules.
A scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell. The movement of macromolecules of polysaccharides or proteins out of or into the cell is known as Bulk transport.
Bulk transport is of two types which include endocytosis and exocytosis whereby both require an expenditure of energy. Exocytosis materials are being exported out of the cell via secretory vesicles.
Golgi complex they do package macromolecules into transport vesicles which travel to and spill its content out of cells. Exocytosis is very much important in the expulsion of waste materials out of the cell and also in products secretion. Endocytosis is the process where materials move into the cell.
 Endocytosis is divided into the three types which include pinocytosis, phagocytosis, and receptor-mediated endocytosis.</span>
