In the complete oxidation of glucose, six co2 molecules are formed per glucose molecule. the number of co2 molecules released by glycolysis is by pyruvate oxidation is and by the citric acid cycle is zero; two; four one; one; four one; two; three zero; zero; six two; two; two

zero, two, four.

Explanation:

In process of glycolysis no carbon dioxide (CO2) molecule is formed. From image 1 it can be seen that although no carbon dioxide is produced but two pyruvate molecules are formed.  Each pyruvate when oxidizes release one CO2 molecule as shown in image 2. Since we have two pyruvate molecules hence two carbon dioxide molecules are released. Double pyruvate oxidization results in two acetyl CoA, the citric acid cycle (Krebs cycle) then breaks down both acetyl CoA and releases four CO2 molecules.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
