How Much Glucose Does a Person Metabolize Climbing a Mountain?

Click For Summary
SUMMARY

The discussion centers on calculating the mass of glucose metabolized by a 59.0-kg individual during a mountain climb with a 1550m elevation gain. It is established that the work performed in the climb is approximately four times the work required to lift the individual by the same height. The enthalpy of formation for glucose (C6H12O6) is given as -1273.3 kJ/mol, which is crucial for determining the energy yield from glucose metabolism. The efficiency of energy conversion during metabolism is noted to be about 70%.

PREREQUISITES
  • Understanding of basic physics principles related to work and energy.
  • Knowledge of glucose metabolism and its chemical equation.
  • Familiarity with enthalpy and thermodynamic concepts.
  • Ability to perform calculations involving mass, energy, and efficiency.
NEXT STEPS
  • Calculate the total work done by the climber using the formula for gravitational potential energy.
  • Research the energy yield from glucose metabolism in kJ per gram.
  • Learn about the efficiency of metabolic processes in humans.
  • Explore the relationship between physical exertion and energy expenditure in climbing.
USEFUL FOR

Students studying physics and biology, fitness enthusiasts interested in energy expenditure, and anyone involved in metabolic research or exercise physiology.

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...
