38 ATP
Which tissues mainly depend on glucose as a source of energy?
Brain
What is the primary function of gluconeogenesis during starvation?
Maintain blood glucose levels
Why is the re-synthesis of glucose from lactate important for acid-base balance?
To prevent metabolic acidosis
Which process supplies glucose to adipose tissue for triacylglycerol formation?
Gluconeogenesis
Why are brain cells particularly sensitive to variations in blood glucose levels?
Because they rely heavily on glucose as an energy source
Test your knowledge on the anaerobic glycolysis pathway and its significance in ATP production under different conditions like lack of mitochondria, non-functioning mitochondria, and severe muscular exercise. Learn about the production of lactate as a byproduct of anaerobic glycolysis.
