Well, probably a non-polar fat soluble molecule, because Ions and Large Polar Molecules cannot.
<h2>GPCRs,RTKs</h2>
Explanation:
G Protein Coupled Receptors(GPCRs) are more common and found in almost all eukaryotes whereas Receptor Tyrosine Kinases(RTKs) are second largest family of receptors that relay signal from cell surface to the interior
- G protein coupled receptors(GPCRs) interacts with the ligand activated GPCR and phosphorylates its intracellular domain.This process of phosphorylation can terminate signal or desensitize receptor
- Autophosphorylation of receptor can initiate signal in case of Receptor Tyrosine Kinases(RTKs);Autophosphorylation is a feature of RTKs in which receptor dimerization activates intrinsic tyrosine kinase activity by which they phosphorylate its own tyrosine residue on cytosolic phase
- Seven transmembrane helices can be seen in case of G protein-coupled receptors(GPCRs);transmembrane protein of it consists of single polypeptide and spans the membrane 7 times
- Insulin receptor is a part of Insulin Signalling which comes under RTKs;Insulin receptor always exist in case of dimeric form
- Epinephrine receptor is an example of GPCRs;Epinephrine is an endocrine hormones produced in stress condition
- Transmembrane protein of GPCR activates G protein,activated G protein binds with effector enzyme and activate it;effector enzyme further can produce or destroy secondary messenger
Answer:
b
Explanation:
earth's ocean did grew higher over time because o rainfall for the last 20 years!
A major greenhouse gas is CO2 and nearly all CO2 gasses come from fossil fuels, except for methane gas and nitrous oxide which comes from waste and are GHGs (which shouldn't be discounted).
Answer: The correct option is D.
All of the above.
Explanation:
This is because complex organisms developed from cyanobacteria and release of oxygen. Cyanobacteria is a blue green algae and first organism that photosynthesized. It uses carbondioxide and water in the presence of the chlorophyll present and light energy to produce carbohydrates and oxygen. The oxygen released into the atmosphere brought about respiration and development of ozone.
This great oxidation event changed the Earth and life on Earth too.
