1.1 Look at the different sports below. Which of the two types of
endurances (anaerobic/aerobic) do you need (most) when you are
doing:
a. worstelen: anaerobic.
b. Skieën: aerobic
c. Rodelen: anaerobic
d. Speerwerpen: anaerobic
e. Tennis: anaerobic
f. Touwtrekken: anaerobic
g. Voetbal: aerobic
h. Triathlon: aerobic
i. Gymnastiek: anaerobic
1.2 A top male cyclist can generate up to 500 J/s when he is exercising
at full aerobic power.
a. How many grams of glucose will this athlete have to use per
hour?
Aerobic: 17Kj energie per gram
17 Kj is 17 000 j
500 j/s 500 x 3600 = 1 800 000 joule per uur
1 800 000/17 000 = 105,9 gram glucose per uur
b. How many grams of glucose will this top athlete have to eat
each hour to compensate for the amount
o of glucose that he is using?
20% = 105,9 gram dus 100% = 529,5 gram
1.3 Look at Eq. 1.2. In this equation the oxidation of glucose is depicted.
Of course, atoms are not wasted during this process. Before and
after the reaction the total amount of atoms of each sort must be
equal. Complete the equation by filling in the right numbers on the
empty spaces.
C6H12O6 + 6O2 6CO2 + 6H2O
1.4 Look carefully at picture 1.5 of a lactic acid molecule.
a. What is the molecular notation of lactic acid? (Write it down in
the form of C?H?O?)
