After differentiation, the various types of cells become specialized for a specific function. Their ______ relates to this _____
kykrilka [37]

Explanation:

The structure relates to their function

Their structural components (i.e. their makeup) determine their function (what they do). In specific cell types, collected proteins may function as a unit called an organelle.

Further Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bound by double membranes make most of the chemical energy required for powering the biochemical reactions within the cell. this chemical energy is stored within the molecule ATP which is produced.

Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they

  • may increase metabolic reaction efficiency;
  • they allow cells to concentrate smaller fractions of enzymes and solutes separate proteins and molecules that may harm the cells by parceling them into membrane-bound organelles
  • for example, hydrolytic enzymes concentrated within vacuoles may degrade macromolecules like DNA and RNA within the cytoplasm.

Any stimulus that opens a ________ ion channel will produce a graded potential.
Fiesta28 [93]

E) All of the answers are correct.

Ion channels are proteins located in the membrane that allow ions to pass through the channel pore. Ion channels can be classified (by what opens and closes the channels) into few groups:

• Voltage-gated channels-open and close in response to membrane potential

Examples: Voltage-gated proton channels, Voltage-gated sodium channels, Voltage-gated potassium channels

• Ligand-gated (neurotransmitter) or ionotropic receptors (ligand binds to extracellular domain of the receptor

Examples: "nicotinic" Acetylcholine receptor, ionotropic glutamate-gated receptors

• Lipid-gated- lipid molecules bind to the  transmembrane domain of the channel

Example: Inward-rectifier potassium channels

• Light-gated channels-like rhodopsin channel that is directly opened by photons

• Mechanosensitive (e.g. stretch, pressure) ion channels.

Does anyone know this answer?
castortr0y [4]
<span>RNA's nucleotides are made of a ribose sugar while DNA's are made from a deoxyribose sugar. The difference is that deoxyribose sugar has one less oxygen than a normal ribose sugar.RNA's nucleotides are composed of Uracil an alternate nitrogenous base to Thymine. So the sequence of nitrogenous bases is composed of Adenine, Uracil, Cytosine, and Guanine opposed to Adenine, Thymine, Cytosine, and Guanine.<span>RNA is mainly found in a single stranded form where it loops around itself. DNA on the other hand is a double stranded helix.
