A mutation in a G-protein prevents the alpha-subunit from dissociating from the beta/gamma-subunit. What effect will this have o
Ymorist [56]

Answer:

the pathway will be under-expressed.

  • the alpha subunit helps to bind with either GDP or GTP. when the α subunit is bound with GDP, it will be bound to β and γ subunits and thus forms an inactive state for G-protein.
  • when the alpha subunit binds with the GTP, it becomes activated and dissociates β and γ subunits.

if G-protein Coupled Receptor is unable from dissociating β and γ subunits, then the pathway will go under expression.  

The chemical qualities of the alpha subunit allow it to bind easily to one of two guanine subunits, GDP or GTP. The protein thus has two functional formations. When GDP is bound to the alpha subunit, the alpha subunit remains bound to the beta-gamma subunit to form an inactive trimeric protein.

G-proteins, cAMP, and Ion Channel Opening. The alpha subunit activates adenylate cyclase, in purple, and loses GTP. Adenylate cyclase converts ATP to cyclic AMP, which then activates Protein Kinase, shown in blue. Protein Kinase phosphorylates an ion channel, letting sodium ions rush into the cell.

As a result of the ligand binding to its site on the G-protein-linked receptor, A) the G-protein changes conformation and GTP replaces the GDP on the alpha subunit. ... Inactivation of the alpha subunit occurs when its own phosphorylase activity removes a phosphate from the GTP.

Licemer1 [7]

A batsman is unlikely to score a century in every cricket match. This is an example of "partial reinforcement".

<u>Option: C</u>

<u>Explanation:</u>

Unlike constant reinforcement, partial reinforcement is only strengthened during certain times or time ratios, rather than emphasizing the action every single time. This method of arranging reinforcement is also called intermittent reinforcement after certain number of correct answers or certain interval of time. Thus here a batsman donot plan intentionally to make a century in every cricket match, but it goes random. Although when they need to score high on pressure, they force themselves to stretch as much possible which is not general.

For humans, linoleic acid is one of the essential fatty acids we must consume. It is plentiful in vegetable oils, and we use it
Rus_ich [418]

Answer:

18 ATP.

Explanation:

Total 18 ATP are produced because 9 FADH2 are converted into 9 ATP molecules and the earlier 9 ATP molecules are already present in the first b-oxidation process. The first Krebs cycle produces 27 NADH, 9 FADH2 and 9 ATP while on the other hand, the second Krebs cycle produces 9 ATP molecules from  9 FADH2 so total it produces 18 ATP molecules.
