Biochemistry: Hormonal Control of Blood Glucose

Biochemistry4 CardsCreated 4 months ago

This deck covers the hormonal regulation of blood glucose levels, focusing on the roles of insulin and glucagon in metabolic processes.

Does insulin promote the movement of glucose into cells or into the blood? Under what circumstances would insulin be released by the pancreas (high or low blood glucose level) and why?

Insulin promotes the movement of glucose into cells. When the blood glucose is too high after a carbohydrate-rich meal, insulin is released by the pancreas to bring glucose into the cells (from the blood), which lowers the blood glucose level.

What types of metabolic reactions does insulin activate? Give examples of metabolic reactions that insulin activates. Options: Glycolysis, gluconeogenesis, glycogenesis, glycogenolysis.
Insulin activates metabolic processes that use glucose to derive energy (glycolysis) or for storage as glycogen (glycogenesis).
Does glucagon promote the movement of glucose into cells or into the blood? Under what circumstances would glucagon be released by the pancreas (high or low blood glucose level) and why?
Glucagon promotes the movement of glucose from the cells into the blood. When the blood glucose is too low after a period of fasting, glucagon is rele...

20 Standard Amino Acids

**20 Standard Amino Acids – 2–3 line description:** Amino acids are the building blocks of proteins, each consisting of an amino group, a carboxyl group, a hydrogen atom, and a variable R group attached to a central carbon. Glycine (Gly) has a hydrogen R group, while Alanine (Ala) has a methyl (CH₃) R group. Both are nonpolar and have aliphatic side chains.

4.2: Diffusion

Diffusion is the passive movement of molecules from a high to low concentration until equilibrium is reached. Factors like concentration gradient, surface area, and diffusion distance affect its rate. Facilitated diffusion involves specific protein channels and carrier proteins that help transport larger or charged molecules across the membrane without using energy.

2.4: Water and it's functions

Water has key properties like high specific heat capacity, high latent heat of vaporisation, and strong cohesion due to hydrogen bonding—making it vital for temperature regulation and transport. It also plays essential roles in metabolism, acts as a universal solvent, and provides a medium for biochemical reactions.

Does glucagon promote the movement of glucose into cells or into the blood? Under what circumstances would glucagon be released by the pancreas (high or low blood glucose level) and why?
Glucagon promotes the movement of glucose from the cells into the blood. When the blood glucose is too low after a period of fasting, glucagon is released from the pancreas to move glucose out of the cells into the blood, which increases the level of glucose in the blood.
What types of metabolic reactions does glucagon activate? Give examples of metabolic reactions that glucagon activates. Options: Glycolysis, gluconeogenesis, glycogenesis, glycogenolysis.
Glucagon activates metabolic processes that make glucose. The examples of the glucose making metabolic processes are gluconeogenesis (makes glucose from a non-carbohydrate source of pyruvate) and glycogenolysis (breaks down glycogen into glucose).
