The carbon atom(s) of pyruvate is(are) first converted to carbon dioxide by pyruvate dehydrogenase complex is the second number of carbon of pyruvate goes to oxidation and convert it to CO2 in Krebs cycle.
<h3>what is Krebs cycle ?</h3>
Krebs cycle is also known as citric acid cycle it is the conversion of sugar to the direct energy in the form of ATP which further goes to mitochondria as it is the power house of the human cell.
Pyruvate molecule release second number carbon from the chain and undergoes oxidation to form the CO2.
Therefore, second number carbon atom will converts to carbon dioxide.

Answer:
a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.
Answer:
2.45Joules
Explanation:
since kinetic energy is K.E.=1/2m
lost in potential energy is gain of kinetic energy
mgh=1/2mv^2
9.8*2*0.5=v^2
=9.8
v=
=3.13m/s
now k.e. = 0.5*m* =0.5*0.5*9.8 =2.45J
Answer:
16 minutes
Explanation:
First, we need to calculate the amount of heat needed to cool the beef stew:
Q = mcΔT
Where <em>m</em> is the mass, <em>c</em> is the heat capacity and <em>ΔT</em> is the variation of the temperature.
Q = 10x4x(40 - 90)
Q = -2000 kJ
So, the beef stew needs to lost 2000 kJ to cool.
With the initial temperature at 90ºC, the rate of cooling(r) will be:
r = 1.955x(90 - 25)
r = 127.075 kJ/min
So, to lose 2000 kJ, will be necessary:
t = Q/r
t = 2000/127.075
t = 16 minutes
