What 3 functions do proteins have in a plasma membrane?*

Biology
1 answer:
Aliun [14]2 years ago
4 0

Answer:

Explanation:

Proteins in the plasma membrane have several functions based on their components, location etc. For instance, if the protein transcends the entire plasma membrane it could be a transport protein, responsible for the import and export of certain molecules between the cell and the extracellular matrix (ECM). If the proteins are resting at the surface of the cell, facing the ECM, their role could be to detect components in the ECM, relaying a series of messages back to the nucleus so that the cell can ‘decide’ what it should do with this information (is it being told it should undergo apoptosis, should it begin to divide, should it migrate?). As well as this, it could be involved in the detection of foreign bodies such as pathogens. This is an extremely job for these proteins because if the cell does come in contact with a pathogen, the cell can use these proteins to engulf the pathogen and through a series of steps, present the antigen on their major histocompatibility complexes (either 1 or 2 depending on the cell type) or HLA’s for human cells. Thus it can be concluded that protein functions vary widely in the plasma membrane and due to the vast number of proteins that can be found there, it’s difficult to narrow down the exact main of functions of all these proteins put together.

Match the classification with the food crop it includes.
SVEN [57.7K]

The correct matches are:

Grains - Rice

The grains are plants that are grass-like. They are one seasonal, and every year have to be seeded again. They produce very small grains which are high in carbohydrates and are very nutritious, so the majority of the world uses them as primary food source. They include rice, wheat, corn...

Roots and tubers - Carrots

The roots and tubers are plants that use their root as storage of sugars. This makes the root become bulky, meaty, and very nutritious. These plants include the carrots, potatoes, ginger, Jerusalem artichoke...

Pulses - Lentils

The pulses are plants with small steams, and small grain-like seeds. These seeds are actually very rich in iron, so they are often used by the people in order to keep the hemoglobin on a good level. They include the lentils, legume, green beans, chickpeas...

Herbaceous - Lettuce

The herbaceous plants have the appearance of wide leafed grasses. They have thick, juicy leaves, and they tend to be rich in lot of vitamins. Very often they are used as salads. These plants include the lettuce, spinach, arugula...

Oil seeds - Sunflower

The oil seeds are thin relatively high grass-like plants. They produce flowers that have oil rich seeds. They are used for producing oil in general. These plants include the sunflower, canola, sesame...

Fiber plants - Jute

The fiber plants are plants that have very thick and strong fibers. They are not really used as a food, but more as a material for making cloths. These plants include the jute, some types of cannabis, cotton...

The complex of dna and protein that makes up a eukaryotic chromosome is properly called __________.
victus00 [196]

The complex of DNA and protein that makes up a eukaryotic chromosome is properly called <u>chromatin .</u>

<u></u>

  • Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells.

What is the chromatin and its function?

  • To create chromosomes, chromatin fibers are coiling and condensing.
  • Numerous cellular functions, including DNA replication, transcription, DNA repair, genetic recombination, and cell division, are made possible by chromatin.

What is chromatin in cell?

  • Chromosomes in eukaryotic cells are made of chromatin, a compound of DNA and proteins.
  • Nuclear DNA is extremely compressed and wrapped around nuclear proteins in order to fit inside the nucleus; it does not exist as free linear strands.

Where is chromatin found?

  • Chromatin is a genetic material or a macromolecule comprising DNA, RNA, and associated proteins, which constitute chromosomes in the nucleus of a eukaryotic cell.
  • This chromatin is located within the cell nucleus.

A nerve poison that blocked neurotransmitter receptors on the dendrites would __________. inactivate the enzyme that degrades th
Svet_ta [14]

The correct answer is: prevent reception of a signal in a receiving neuron

Neurotransmitters are signal molecules or chemical messengers which transmit signals across a chemical synapse. Neurotransmitters send the signal, from one neuron (nerve cell) to another neuron, from neuron to muscle cell (motor plate), or from neuron to gland cell.

Drugs that bind to neurotransmitter’s receptor can have two effects on its action:

• Antagonists-they bind to receptor and thus prevent a neurotransmitter from binding to it

• Agonists-they bind to receptor and mimic the normal neurotransmitter (have the same effect as neurotransmitter).
