What are the similarities and differences between carrier proteins and channel proteins​
kvv77 [185]
* Channel proteins- these are proteins with a hydrophilic pore where specific ions are able to pass through the membrane. Each channel protein is specific to an ion. This is the only way ions can travel through the membrane. They are trans membrane proteins.

* Carrier proteins- these are proteins which allow larger or polar molecules through the membrane. They are trans membrane proteins.

Carrier proteins essentially “carry" signals that are not soluble in aqueous solution through the blood stream to their target cells. Carrier proteins for hydrophilic signals prevent degradation of the signal. Channel proteins are embedded in cell membranes. They often are receptors (though not always), and when activated, allow specific ions to pass through the membrane.

A channel protein is a special arrangement of amino acids which embeds in the cell membrane, providing a hydrophilic passageway for water and small, polar ions. Like all transport proteins, each channel protein has a size and shape which excludes all but the most specific molecules

The carrier protein facilitate diffusion of molecules across the cell membrane. The protein is imbedded in the cell membrane and covers the entire membrane. This is important because the carrier must transport the molecule in and out of the cell.

What is the best description of what viruses are made of?
Mazyrski [523]

The answer is C.

A virus is made up of or consists of a nucleic acid in varying quantity which may either be RNA or DNA.

The nucleic acid is surrounded by a protein shell called a capsid. The word capsid comes from the Latin word  capsa which means box.The capsid and the nucleic acid within it are together referred to as nucleoprotein.The  capsid is made up of small sub units called capsomeres.

In many viruses, the nucleoprotein makes up the whole virus. More complex viruses have one or more further enclosing structures also made mostly of protein. These structures are referred to as envelopes and each envelop is specific to a particular virus.

What does paleontology, biogeography, embryology, and anatomy reveal bout evolution
Ugo [173]

Paleontology deals with fossils and helps in learning the changes of living organisms in sequence.

Biogeography deals with the distribution of species across the mother earth.

Embryology deals with the study of the similarities and difference that exists in the embryos of different species or organisms.

Anatomy deals with the study of the similarities and difference that exists among different species or organisms.

<u>Explanation: </u>

As an organism dies, the remaining of these organisms will be buried in soil. These are fossils. Paleontology supports evolution with the information that are related to the fossils, footprints etc. With these we can study the evolution of organisms and also the changes they undergo. There are some technologies like radiometric dating that can be used for the determination of these rocks and fossils ages.

Charles Darwin suggested that the evolution of species were form their ancestor. Biogeography supports evolution by explaining about the distribution of different species over the earth. Embryology and Anatomy supports evolution by describing about the similarity and difference in the species of living organisms. Embryology deals with the embryos and anatomy deals with the structure.

Which of the following statements concerning carbohydrates associated with the plasma membrane is correct? (eText Concept 7.1)
Ksju [112]

Answer:

The correct answer is : * Membrane carbohydrates function primarily in cell-cell recognition.

Explanation:

The carbohydrates (poly or oligosaccharides) associated with the plasma membrane, are covalently bound to it (to proteins or lipids). They are found in the outer part of the plasma membrane forming the glycocalix. Its main functions are:

-Cell recognition

-Support to the membrane.

emmainna [20.7K]

Answer:

of folded proteins

Explanation:

In Secondary structures; the irregular loops seems to be positioned on the outside of folded proteins while the Alpha and beta sheets is categorically positioned at the centre or interior of the protein.

The loops are positioned on the outside of folded proteins in order for the peptide bonds to be open to form H bonds with water.
