Chapters 1 and 2 part II Flashcards
Fats serve what function?
They store energy in living systems
What are the 3 main types of lipids?
Fats
Phospholipids
Steroids
Which macromolecule has the widest range of functions?
A protein
This is what stores and transmits our genetic information
DNA
What is an amino acid?
It is the monomer of a Protein.
What is the function of a carbohydrate?
Provides energy and play a huge STRUCTURAL and STORAGE role within cells.
What are the Nucleic Acids plymers and monomers known as?
Monomer is a nucleotide, and a chain of monomers is known as polynucleotides
The polymer of a carb is what?
Polysaccharide
A simple sugar is known as what and is a part of which organic molecule?
Monosaccharide of a carbohydrate.
The monomer of a carbohydrate is aka what?
A simple sugar or a monosaccharide
Which molecule provides energy and helps in the structure and storage of a cell?
A carbohydrate
What are the 4 organic molecules in living organisms known as and what are they?
carbohydrates, proteins, nucleic acids, Lipids
What is the protein monomer known as?
Amino acid
What helps translate and express genetic information?
RNA
What is a chain of amino acids called?
Polypeptide
Which elements serves as the skeleton for all organic molecules?
Carbon
Which organic molecule is not a macromolecule?
Lipids
How are lipids different from other organic molecules?
They are relatively smaller and do not have a monomer or polymer.
-They are partially or fully hydrophobic.
What is a polypeptide?
The polymer of protein, or the a chain of amino acids.
This moldecule can act as storage, a receptor, enzymes, muscle contractions:
Proteins.
How are the electrons arranged in carbon atom?
6 electrons, 2 on inner, 4 on outer.
WHat are macromolecules and name them?
They are a large complex organic molecule composed of many repeated subunits.
These are of the four major organic molecules and include Carbs, Nucleic acids, and proteins.
What functions do phospholipids serve?
Make up the cell membrane and help keep things out but are SELECTIVELY PERMEABLE.
This is composed of sugars that provide the major source of energy for daily activities and have some role in cell structure.
Carbohydrates defined.
What are proteins made up of?
Amino Acids?
What are the two types of steroids?
Cholesterol
and
Sex Hormones.
