Answer:

The cell membrane is semi-permeable. It allows some molecules to enter easily inside the cell whereas some molecules are blocked from entering the cell.

Small, polar molecules and hydrophobic molecules enter easily through the cell membrane. But large molecules and ions cannot easily move inside the cell membrane.

A hydrophilic substance like the substance L mentioned in the question enters the cell membrane through the help of carrier proteins. The substance attached to the large protein might enter through active or passive diffusion but it can only enter the cell by attaching to carrier proteins.

Examples of membrane receptors:

  • Ligand, located outside the cell
  • Ligands are connected to specific receptor proteins based on the shape of the active site of the protein.
  • The receptor releases the second messenger after the ligand is connected to the receptor.

<h2>Further Explanation </h2>

In biochemistry and pharmacology, receptors are protein molecules that receive chemical signals from outside the cell.

Receptors can be bound to cell membranes, cytoplasm, or the nucleus, each of which can only be attached by certain types of signaling molecules. Signaling molecules attached to a receptor are called ligands, which can be a peptide or other small molecules such as neurotransmitters, hormones, drugs, or toxins.

Receptor proteins can be classified by their location. Transmembrane receptors include receptors connected with ion channels (ionotropic), receptors connected to protein G (metabotropic), and receptors connected with enzymes.

Not every ligand that binds to the receptor also activates the receptor. The ligand class can be divided into:

  • Agonist (full)
  • Partial agonist
  • Antagonist
  • Inverse agonist
  • Allosteric modulator

Receptors capable of producing biological responses in the absence of bound ligands are said to display "constitutive activity".

What produces 32 ATP molecules
Vlad [161]

Explanation:

In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain.

Where is the meristem located?
bezimeni [28]

Answer:

Meristems are classified by their location in the plant as apical (located at root and shoot tips), lateral (in the vascular and cork cambia), and intercalary (at internodes, or stem regions between the places at which leaves attach, and leaf bases, especially of certain monocotyledons—e.g., grasses).

Which statement best describes the social status of women in ancient Egypt? Women were viewed as the lowest social class. Women
Usimov [2.4K]

Answer:

In ancient Egypt, women were given many of the same rights as men.

Explanation:

The women in ancient Egypt were in no way seen as the lowest social class, so this statement is not correct.

The women were allowed by law to do pretty much everything as the men, so their status was not dependent on their husbands, so it is not a correct statement.

The women were equal in front of law in ancient Egypt, as well as being able to do the same things as men, so this statement is correct.

Women did not have the same status as their fathers, so this is not a correct statement.
