Question 1:  Where does fatty acid synthesis primarily occur within the cell? Answer: Fatty acid synthesis occurs in the cytosol of the cell. This is in contrast to fatty acid oxidation, which primarily occurs in the mitochondria. Question 2: What is the primary product of fatty acid synthesis? Answer: The primary product of fatty acid […]

Gluconeogenesis is a vital metabolic process that allows the body to synthesize glucose from non-carbohydrate sources, ensuring a continuous supply of glucose, especially during fasting or intense exercise. Below, we explore how key substrates enter gluconeogenesis and the role of specific enzymes with easy-to-remember mnemonics to simplify learning.   Figure 1: Gluconeogenesis and Its Connection
