Why is my heart rate high after exercise?
Why is my heart rate high after exercise? This is mainly due to a decline in physical fitness. State of training: your sympathetic nervous system is more active during recovery than when you’re well recovered.

Why do liver cells have lots of mitochondria?
Why do liver cells have lots of mitochondria? The liver is a central organ for the homeostasis of carbohydrates, lipids and proteins metabolism. In this context, hepatocyte mitochondria are essential in regulating the flux of metabolites in the cell in order to adjust energetic demand, ammonia detoxification, or anabolic pathways. Why would mitochondria in heart […]
