Each hemoglobin molecule is made up of four heme groups surrounding a globin group, forming a tetrahedral structure
This is all I know about this, let me know if you still have questions ;)
<u>Answer:</u>
Effects Include:
Activates secondary messengers such as cAMP which further activates number of hormones like
- ADH: production of this hormone causes kidneys to retain more water inside body.
- GHRH: release growth factors and stimulates growth of organism.
- ACTH: produces fight or flight responses i.e rise in heart beat, rise in Blood pressure etc
- TSH: Stimulate the synthesis of Thyroid hormone and enhances the metabolism of body. In rare cases causes Goiter without the deficiency of Iodine.
- LH: Stimulate follicle maturation and formation of ovules in women.
- Calcitonin: Decreases blood calcium level by deposition calcium in bones. This effect weakens the muscles.
- Glucagon: Stimulates glycogen breakdown from liver and muscles and many more effects.
<u>Explanation:</u>
Background Knowledge:
GPCR (G Protien coupled receptors) are present inside plasma membrane in huge amount. As name suggest that these receptors are coupled with G proteins during their inactive state present inside of the cell. During their Inactive state these G proteins are bounded with GDP molecule.
Upon receiving signal molecules from outside of cell alters the shape of GPCR. These receptors also triggers change in G Protein, as a result of this GTP get attached with them. This protein further activates reaction cascades inside of the cell.
What happen if GTP cannot be hydrolyzed to GDP + Pi?
If GTP cannot hydrolyzed in to GDP + Pi than, it cannot be able to dissociate from G proteins. Cascade system doesn't stop and produces many effects on body.

True. A human haploid cell contains contain only one complete set of chromosomes (23). Meanwhile, a diploid cell has 2 set of chromosomes from the parents, thus containing 46 chromosomes.
Answer:
The beginning and majority of the time is known as Interphase. Interphase is 80% of the total cycle and is where the cell does most of the work in replicating organelles, chromosomes, and preparing to undergo Mitosis which is the actual splitting process where one cell becomes two. During Interphase there are 3 major steps, G1, S, and the G2 phase.
Explanation:
Protista organisms are most closely related to Archaebacteria.
