Why are autosomal genetic disorders usually recessive

Biology
1 answer:
Sever21 [200]3 years ago
3 0
<span>Autosomal recessive is one of several ways that a trait, disorder, or disease can be passed down through families. An autosomal recessive disorder means two copies of an abnormal gene must be present in order for the disease or trait to develop</span>

A) Compare and contrast diffusion, passive transport (diffusion &amp; facilitated), primary active transport and secondary activ
zheka24 [161]

Answer:

<u>Passive transport</u>: It does not need any energy to occur. Happens in favor of an electrochemical gradient. Simple diffusion and facilitated diffusion are kinds of passive transport.

<u>Simple diffusion</u>: molecules freely moves through the membrane.

<u>Facilitated diffusion</u>: molecules are carried through the membrane by channel proteins or carrier proteins.

<u>Active transport</u> needs energy, which can be taken from the ATP molecule (<u>Primary active transport</u>) or from a membrane electrical potential (<u>Secondary active transport</u>).

Explanation:

  • <u>Diffusion</u>: This is a pathway for some <em>small polar hydrophilic molecules</em> that can<em> freely move through the membrane</em>. Membrane´s permeability <em>depends</em> on the <em>size of the molecule</em>, the bigger the molecule is, the less capacity to cross the membrane it has. Diffusion is a very slow process and to be efficient requires short distances and <em>pronounced concentration gradients</em>. An example of diffusion is <em>osmosis</em> where water is the transported molecule.
  • <u>Facilitated diffusion</u>: Refers to the transport of <em>hydrophilic molecules</em> that <em>are not able to freely cross the membrane</em>. <em>Channel protein</em> and many <em>carrier proteins</em> are in charge of this <em>passive transport</em>. If uncharged molecules need to be carried this process depends on <em>concentration gradients</em> and molecules are transported from a higher concentration side to a lower concentration side. If ions need to be transported this process depends on an <em>electrochemical gradient</em>. The <em>glucose</em> is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.

<em>Simple diffusion</em> and <em>facilitated diffusion</em> are <u>passive transport</u> processes because the cell <u><em>does not need any energy</em></u> to make it happen.

  • <u>Active transport</u> occurs <em>against the electrochemical gradient</em>, so <u><em>it does need energy to happen</em></u>. Molecules go from a high concentration side to a lower concentration side. This process is always in charge of <em>carrier proteins</em>. In <u>primary active transport</u> the <em>energy</em> needed <em>comes from</em> the <em>ATP</em> molecule. An example of primary active transport is the <em>Na-K bomb</em>. In <u>secondary active transport</u>, the<em> energy comes from</em> the <em>membrane electric potential</em>.  Examples of secondary active transport are the carriage of <em>Na, K, Mg metallic ions</em>.
