How Much Glucose Does a Person Metabolize Climbing a Mountain?

In summary, the metabolism of glucose produces CO2 and H2O and converts heat to work with 70% efficiency. We can use the enthalpy of formation of C6H12O6 to calculate the amount of work done by a 59.0-kg person in climbing a mountain with an elevation gain of 1550m, assuming that the work performed is four times that required to simply lift 59.0 kg by 1550m. This can be solved using basic physics principles.

Homework Statement



The metabolism of glucose, C6H12O6, yields Co2(g) and H2O(l) as products. Heat released in the process is converted to useful work with about 70% efficiency.

Calculate the mass of glucose metabolized by a 59.0-kg person in climbing a mountain with an elevation gain of 1550m . Assume that the work performed in the climb is about four times that required to simply lift 59.0 kg by 1550m .

Homework Equations



(enthalpy of formation of C6H12O6(s) is -1273.3 kJ/mol.)

The Attempt at a Solution



Im so confused with this question and i do not even know where to start...Any help will be appreciated...

1. How is glucose metabolized in the body?

Glucose is metabolized through a series of chemical reactions known as glycolysis. In this process, glucose is broken down into smaller molecules, producing energy in the form of ATP.

2. What enzymes are involved in the metabolism of glucose?

Enzymes play a crucial role in the metabolism of glucose. Some important enzymes involved include hexokinase, phosphofructokinase, and pyruvate dehydrogenase. These enzymes help catalyze the various chemical reactions in the process.

3. How does the body regulate glucose metabolism?

The body has several mechanisms in place to regulate glucose metabolism. Insulin and glucagon, hormones produced by the pancreas, help maintain blood glucose levels by signaling the liver to store or release glucose. Additionally, enzymes involved in glycolysis are regulated through feedback mechanisms to ensure the process runs smoothly.

4. What are the end products of glucose metabolism?

The end products of glucose metabolism vary depending on the type of cell and oxygen availability. In aerobic conditions, the end products are ATP, carbon dioxide, and water. In anaerobic conditions, the end products are lactic acid and ATP.

5. How does glucose metabolism contribute to overall health?

Glucose metabolism is essential for providing energy to the body's cells. It also helps maintain blood glucose levels, which is crucial for proper brain function. Dysfunction in glucose metabolism, such as in diabetes, can lead to serious health complications.
