The chemical context of life Flashcards
1
Q
Hemoglobin
A
carry oxygen through blood cells
-uses iron to bond
-works better in warm climates
-contains iron surrounded by atoms of carbon, nitrogen and hydrogen
-binds with oxygen co-opertivly all the time
2
Q
chemosynthesis
A
Archaea-found in really low/high temps
-little to no oxygen
-no light
3
Q
Hemocyanin
A
-uses copper to bond O2
-low O2
-cold environment
-blue blood
4
Q
ionic bonds
A
-bond between a cation and anion
-transfers electron (so full outer shell)
-atom that takes electron is more electronegative
5
Q
Covalent bond
A
-shared electrons
6
Q
polar covalent
A
unequal sharing of electrons
7
Q
non-polar covalent
A
equal sharing of electrons
8
Q
hydrogen bonds
A
-weak bond between Hydrogen atom of one water molecule and Oxygen atom of another water molecule
