This activates specific receptors called cannabinoid receptor.This receptors are found in limbic and cerebral cortex region and cerebellum.

As these receptors are located in the brain, the effect of these receptors are also wide spread.In healthy brain, these receptors are activated by a neurotransmitter called as anandamide that have pain relieving effect and also play important function in brain.When THC activates these receptors,causes interference of the normal function.

marijuana also boost another type of neurotransmitter called dopamine after taking the drug.

  • pH levels in the body (I.e. the stomach)
  • wanted levels
  • sugar levels
  • level of Co2 in our bodies
  • blood glucose levels
  • body temperature

we maintain homeostasis to ensure that our enzymes, which speed up or make chemical reactions are working well and work within he required conditions.

external things we can do to maintain homeostasis:

  • wearing the appropriate clothing in summer and winter
  • consuming the correct temperature beverages (i.e. cold drinks in summer)
  • consumitn the correct temperature and nutrient required foods (I.e. nutritious pumpkin soup in winter)

we also shiver when we are cold - the friction between our muscles produces heat.

Explain why the steroid hormone estradiol (MW 272) readily crosses membranes by simple diffusion but the much smaller H requires
bazaltina [42]

Answer:

Estradiol has a higher partition coefficient than H+ ions

Explanation

Estradiol is a non-polar and hydrophobic molecule that has a higher partition coefficient than H+ ions, it means that the cell membrane is more permeable to this molecule because it can dissolve in and diffuse within the hydrophobic phase of the membrane. The movement of polar charged molecules (even small H+ ions) requires the input of energy to be able to dissolve within the lipid bilayer. In consequence, the movement of H+ ions requires proteins capable of transporting these protons through the membrane.
