What is a ligand? what do ligands have to do with receptor-mediated endocytosis?
Volgvan
In biochemistry, aligand is a substance that forms a complex with a biomolecule to serve abiological purpose. In protein-ligandbinding, the ligand is usually a molecule which produces a signal by binding to a site on a target protein.

Receptor mediated endocytosis is an endocytotic mechanism in which specific molecules are ingested into the cell. The specificity results from a receptor-ligand interaction. Receptors on the plasma membrane of the target tissue will specifically bind to ligands on the outside of the cell. An endocytotic process occurs and the ligand is ingested.

A very well studied example of receptor mediated endocytosis involves the metabolism of cholesterol.

maw [93]

Complete Question:

1. Organisms don’t all reproduce the same way. However, by comparing the ____ of these organisms, many similarities between them are ____

2. of these organisms, many similarities between them are revealed. These similarities suggest that they’re ___ linked. This type of study is called developmental biology.

Group of answer choices.

A) Cells B) Embryos C) Mode of reproduction D) Evolutionarily. E). Revealed.

Answer:

embryo; revealed; evolutionarily.

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.

II. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.

It's a fact that all living organisms do not reproduce the same way.

However, by comparing the embryo of these organisms, many similarities between them are revealed. These similarities suggest that they’re evolutionarily linked.

Hence, we refer to this type of study as developmental biology

What kind of channels are located in the input region?
tamaranim1 [39]

Answer:

The correct answer is option B ( ligand gated channels opened by neurotransmitter molecules).

Explanation:

Input region or postsynaptic region or dendrite is the site of neuron cell which receives the impulse from the pre-synaptic neuron at the synaptic junction.

The cell membrane of the dendrite is embedded with ligand-gated channels which opens up in response to the ligand (neurotransmitters) produced by the neurotransmitter vesicle of axon or output region of neuron.

The neuromuscular junction is such a case where acetylcholine receptors present in the dendrite opens in the presence of acetylcholine.

Thus, option B ( ligand-gated channels opened by neurotransmitter molecules) is the correct option.
