Answer: You will need to use the chemical formula of the compound and the average atomic masses from the periodic table to calculate molecular mass . Explanation:Let's look at the example of water. I'll round average atomic masses to two places beyond the decimal. You should adjust your rounding based on your teacher's preferences. H2O = two atoms of H and one atom O in a single molecule H = 1.01 (use the average atomic mass from the periodic table) O = 16.00 To find molecular weight: H = 1.01 x 2 = 2.02 (have to multiply by two since water has two hydrogen atoms) O = 16.00 x 1 = 16.00 The total molecular weight is 18.02 - this was found by adding the total mass from H with the total mass from O. This will also be the molar mass of water Here are a couple more examples: I hope this helps!
DNA -> RNA -> protein
Q: Can a cell produce enough ATP to persist by using glycolysis alone?
A:Yes! Explanation: There is a category of bacteria called obligate anaerobes . These are bacteria which are actually poisoned by oxygen. They generate all of the energy they need using glycolysis. The pyruvate formed in glycolysis is not broken down by the Kreb's cycle and electron transport chain. The pyruvate is broken down using fermentation pathways such as lactic acid fermentation. Anaerobic respiration only produces 2 ATP molecules for every glucose molecule, that is definitely less than the 36-38 ATP produced by aerobic cellular respiration , but cells can survive on this. This video below provides more information about cellular respiration. Hope this helps! |
