What is the main cause of lactic acidosis in the context of tissue hypoxia?
Which glucose transporter is primarily responsible for providing basal glucose to many cells?
Why does anaerobic glycolysis increase lactate production?
Lactic acid produced by anaerobic glycolysis can be converted back to glucose in the liver via gluconeogenesis.
Sodium-dependent glucose transporters (SGLTs) use facilitated diffusion to move glucose across membranes.
GLUT3 in neuronal cells ensures a constant high concentration of glucose required by the brain.
