warm up questions .4 Flashcards
What are the four basic types of macromolecules?
Proteins- (polymers of amino acids)
Carbohydrates -(polymers of sugars)
Lipids -(polymers of lipid monomers)
Nucleic acids -(DNA and RNA; polymers of nucleotides)
What is the monomer of a nucleic acid?
Nucleotide
What are two examples of nucleic acids?
DNA Deoxyribonucleic acid, also known as DNA, is a well-known component in genetics. …
2. RNA Ribonucleic acid, or RNA, is also present in the nuclei of living things, although there are certain types of RNA viruses that only contain RNA, and not DNA
What are the two types of pentose sugar in nucleotides, and how are they different?
ribose (C 5 H 10 O 5) and
deoxyribose (C 5 H 10 O 4)
What are the five general types of nitrogen-containing bases in nucleotides?
adenine (A),
guanine (G),
cytosine (C),
thymine (T),
uracil (U).
Which nitrogenous bases are in RNA?
adenine, guanine, cytosine and uracil.
Which nitrogenous bases are in DNA?
adenine, cytosine, guanine and thymine
What three atoms are in carbohydrates?
Carbon
hydrogen
oxygen
What is the difference between a monosaccharide and a disaccharide?
Are these macromolecules?
Monosaccharides are made of one simple sugar submit (mono=one), disaccharides are made of two subunits (di=two)
yes
What is the function of starch and glycogen?
Energy storage
Why are starch and glycogen good energy sources?
they are easily digested by organisms.
What is the function of chitin and cellulose?
strength and protection of organisms.
Why are fats and oils good energy sources?
fats are an efficient form of energy, the body stores any excess energy as fat
What are the differences between saturated and un-saturated fats?
Saturated fats are bad/unhealthy fats.
They are the type of fats that have double bonds.
unsaturated fats there is at least one double bond in the fatty acid.
What does it mean to say that a molecule is “amphipathic”?
chemical compounds containing both polar and nonpolar (apolar) portions in their structure.
