Explain the process of how hormones trigger the release of fatty acids from adipose tissue.

Answer explanation

Hormones such as adrenaline, glucagon, and ACTH bind to receptors on the surface of adipose cells, activating adenylyl cyclase. This enzyme facilities the conversion of adenylyl cyclase to cAMP utilizing ATP, which then activates protein kinase A. Activated PKA phosphorylates and activates hormone-sensitive lipase (triacylglycerol lipase), which hydrolyzes triacylglycerols to release fatty acids. Additional lipases (diacylglycerol lipase and monoacylglycerol lipase) further break down the remaining glycerides to yield more free fatty acids and glycerol. These fatty acids are then released into the bloodstream, where they are transported by serum albumin to tissues for energy use.

What does an enzyme's effect on the activation energy and the gibbs free energy of a reaction?

Answer explanation

An enzyme is designed to lower the activation energy of a reaction, thereby increasing its rate. However, it has no effect on the free energy (ΔG) change of a reaction. Enzymes only influence the kinetics of a reaction and NOT the thermodynamics.

What is the Ka of an acid with a pka of 6.77?

Answer explanation

What is this structure? Name all of its components and describe its function.

Answer explanation

This is ATP synthase.

1 - F1

2 - Central Stalk (rotor)

3 - Peripheral Stalk

4 - Fo

This structure is found in the inner mitochondrial membrane and facilitates the generation of ATP by pumping protons back into the matrix following the electron transport chain, utilizing energy harvested from the proton motive force.
