If it is not an isotope then it has around 21 neutrons
During glycolysis is used glucose, ADP and pyruvate and produce ATP, water and NADH.
<h3>What is glycolysis?</h3>
Glycolysis is the first step of cellular respiration by which glucose is used to generate energy in the form of ATP.
Cellular respiration has three sequential steps, i.e., glycolysis, the Krebs cycle and oxidative phosphorylation.
Glycolysis is the cellular respiration step that generates 2 net high energy ATP molecules and 2 reduced NADH.
In conclusion, glycolysis uses glucose, pyruvate and ADP to generate ATP, water and Nicotinamide adenine dinucleotides (NADH).

Answer:
A. The cost of producing a kilowatt of power with fuel cell will be less than $30 in 2015
The correct option is A.
To calculate the binding energy, you have to find the mass defect first.
Mass defect = [mass of proton and neutron] - Mass of the nucleus
The molar mass of thorium that we are given in the question is 234, the atomic number of thorium is 90, that means the number of neutrons in thorium is
234 - 90 = 144.
The of proton in thourium is 90, same as the atomic number.
Mass defect = {[90 * 1.00728] +[144* 1.00867]} - 234
Note that each proton has a mass of 1.00728 amu and each neutron has the mass of 1.00867 amu.
Mass defect = [90.6552 + 145.24848] - 234 = 1.90368 amu.
Note that the unit of the mass is in amu, it has to be converted to kg
To calculate the mass in kg
Mass [kg] = 1.90368 * [1kg/6.02214 * 10^-26 = 3.161135 * 10^-27
To calculate the binding energy
E = MC^2
C = Speed of light constant = 2.9979245 *10^8 m/s2
E = [3.161135 * 10^-27] * [2.9979245 *10^8]^2
E = 2.84108682069 * 10^-10.
Note that we arrive at this answer because of the number of significant figures that we used.
So, from the option given, Option A is the nearest to the calculated value and is our answer for this problem.
