What must be removed to make monomers into polymers?
Enough atoms to create bonding sites. Cellulose is an easy one. Its monomer is glucose. The formula for glucose is C6H12O6. To allow a glucose molecule to form part of a cellulosic structure, the tree has to "dehydrate" it by removing a hydrogen atom from one end and a hydroxide ion from the other end. You're left with C6H10O5, which then bonds with another like molecule and another and another.
What compound is the source of the carbon and oxygen atoms in the sugars?
Carbon and oxygen atoms in sugars are sourced from carbon dioxide (CO2) during the process of photosynthesis in plants. Plants absorb CO2 from the atmosphere and convert it into glucose through the Calvin cycle.
Draw and name the enantiomer of D-glucose?
The enantiomer of D-glucose is L-glucose. It has the same molecular formula and structure as D-glucose but differs in the spatial arrangement of atoms, specifically at the chiral carbon (C5) where the hydroxyl group is oriented differently.
Does nuclear fission occur in the heavier elements after a star's death?
I believe that yes, it should occur - assuming any atoms are left. Please note that in the case of a neutron star, most of the atoms are crushed out of existence - i.e., there are no more atoms left, except a few in the outermost layers. Similarly, in a black hole, no atoms will be left.
How many oxygen atoms are left after photosynthesis?
