Molecules of life
While viewing the Bozeman Science video titled “Biology” complete the
following questions. You might want to watch the video once through, then
watch it a second time stopping it as needed to complete your worksheet.
1. We eat ___________ and it’s building blocks are weaved together to make a _______________
thing.
2. _______________ in the burger are broken down into __________ ___________ and these make
proteins in people like you.
3. The sugars that are used to make _________________________ in the bun are broken down into
sugars and used in _______________________ ________________________ to make _________ to move
materials inside you.
4. The ________ inside the burger is used to make ____________ of the ________ membrane of us.
5. Life is built on ___________________. The reason why is that carbon has ________ valence
_________________. So carbon is really good at ____________________. Carbon makes fairly large,
stable molecules and that’s why we are ________________ based.
6. Life is made up of huge ________________ _______________. On the outside of those chains are
__________________ groups. They give ____________________ to the chemical group.
7. The carboxyl group is ______________ and the amino group is ____________. ________________
is needed to make _____________ ______________ which make _______________________.
8. _____________________ is PO4 and is part of _____________.
9. Most molecules are ______________________, which are made up of _________________
Monomers are __________________ blocks and polymers are large ____________________________.
10. There are only _____ polymers and they are built through a process called __________________
synthesis; removing a molecule of _________________ forms a bond.
11. Breaking down polymers involves _____________________. Add ______________ in the middle of
a molecule to ______________ the bond.
THERE ARE FOUR MAJOR MACROMOLECULES:
NUCLEIC ACIDS
12. Two kinds of nucleic acids are ___________ and ______________. DNA stores
_________________________ inside the cell.
13. Both are polymers and their building blocks are ______________________. Each nucleotide has
a base, a _______________ and a phosphate group.
14. We get our DNA by eating _____________, breaking it down into monomers, then
building polymers.
Proteins
15. These are made of an ____________ group and a _______________ group, then a H, N,
and an side chain. The R group is different for each ______________ acid. We have ____
amino acids that are needed by humans to ___________________.
16. Proteins are huge three dimensional structures that sometimes are made up of
_____________________ of ______________ acids attached together. Proteins have a
specific shape which will give the protein its function.
Lipids
17. These can be used to build _____________________ and give us ____________.
18. Lipids can be ____________________ or _________________________. Saturated will have
_______________________ around the molecule. Unsaturated will have a ______________
bond in the middle, and tend to be a ___________________ at room temperature, like
olive ___________.
Carbohydrates
19. Carbs come in 3 types; monosaccharides, disaccharides , and ______________________.
20. Starch in the form of potatoes or ______________ are a bunch of ___________________
molecules.
21. Starch is broken down using ____________________ so that we can use the _________________
in _____________________________.
