Energy Flow in the Life of a Cell Case
Study Energy Unleashed
- The 20,000-plus runners in the New York Marathon collectively
expend more than 50 million Calories worth of energy.
- New York Marathon and many different people running.
- Is a 26-mile journey.
- Is a 26-mile journey.
- What exactly is energy? Do our bodies use it according to the same
principles that govern energy use in the engines of cars and
airplanes? Why do our bodies generate heat, and why do we give off
more heat when exercising than when watching TV?
- The marathoner´s muscles are only about 25% efficient in
converting chemical energy into movement.
- The other 75% is lost as heat.
- Heat to rise their body
temperatures by about 1 ° C every 5
minutes,
- The other 75% is lost as heat.
- Glycogen is the fuel for muscles.
- Glycogen is broken down into glucose
molecules and tehn it breaks down
into carbon dioxide and water and
energy.
- Exergonic (to release) cehmical rwactions
- The excess heat energy released by the exergonic
chemuical reactions in their muscles.
- The excess heat energy released by the exergonic
chemuical reactions in their muscles.
- Carbon dioxide is exhale and watee is lose as sweat.
- Exergonic (to release) cehmical rwactions
- Glycogen is broken down into glucose
molecules and tehn it breaks down
into carbon dioxide and water and
energy.
- During the race, a marathoner burns a great deal of glucose to provide enough
ATP to power muscles through roughly 34,000 running steps.
- People store glucose molecules in the muscles and liver.
- Adults stores 3.5 ounces (100 grams) of
glycogen in the liver and 9.9 ounces (280
grams) in muscles.
- Adults stores 3.5 ounces (100 grams) of
glycogen in the liver and 9.9 ounces (280
grams) in muscles.
- Trained distance athletes may have their liver glycogen storage
capacity increased by more than 50%, and the ability of their
muscles to store glycogen man be more than double that of
nonathletes.
- People store glucose molecules in the muscles and liver.
- Glycogen storage is essential for marathon runners.
- Often about 90 minutes into the race the runner may experience
extreme muscle fatigue, loss of motivation, and even hallucionations.
- Musclrs and brain are starved of energy.
- Htting the wall or bonking.
- Musclrs and brain are starved of energy.
- Often about 90 minutes into the race the runner may experience
extreme muscle fatigue, loss of motivation, and even hallucionations.
- To store the greatest possible amount of glycogen, endurance athletes
practice carbo-loading by consuming great amounts of carbohydrates
(starches and sugars) during the 3 days preceding the race.
- Packing their liver and muscles with glycogen before the race and consuming energy drinks.
- Packing their liver and muscles with glycogen before the race and consuming energy drinks.
