Insulin has more than one non-reducible forms and has three subunits: alpha, beta, and gamma. Alpha is 135,00 Mr, beta is 95,000 Mr, and gamma is 210,000 Mr. The two major parts of the molecule are alpha and beta particles while gamma particles are minor.
The answer is True. The energy from the higher temperature goes to the object of lower temperature.
Hope this helped!
Answer:
A substance will enter into a cell through diffusion if a concentration gradient is present. The process of diffusion will only occur if the concentration of a substance is higher outside the cell as compared to the inside of the cell. Diffusion is the movement of particles along the concentration gradient i.e from an area of higher concentration to an area of lower concentration.
The movement of molecules against a concentration gradient is termed as active transport.
