Question

You are running away from an angry dog, much faster and farther than you are used to running. What causes you pain?
(1 point)
O lactic acid fermentation
O citric acid cycle
O Calvin cycle
O electron transport chain

Answer 1

The most likely cause of pain in this scenario would be lactic acid fermentation. When you run faster and farther than you're used to, your muscles have an increased demand for energy. If the demand surpasses the rate at which oxygen can be supplied to the muscles, lactic acid fermentation occurs as a way to produce ATP without oxygen. This process can build up lactic acid in your muscles, leading to pain and discomfort. The citric acid cycle, Calvin cycle, and electron transport chain are not directly related to the immediate pain you may experience while running away from a dog.
