Macromolecules
These are the four major macromolecules
What are lipids, proteins, carbohydrates and nucleic acids?
This element is found in all organic (macromolecule) compounds
What is Carbon?
What bases pair with each other in DNA?
A-T, C-G
This is the brain of the cell
What is the nucleus?
Movement of molecules from high to low concentration; requires no energy.
diffusion
Nucleotides are the building blocks of these
What are Nucleic Acids?
Name two differences between DNA and RNA.
what sugar, double/single stranded, U vs. T
The function of the mitochondria.
convert food into energy.
Movement from low to high; requires energy.
active transport
These are made of many monomers
What are polymers?
What happens during transcription?
mRNA made
This organelle selectively allows materials in and out of the cell
What is the cell/plasma membrane?
Movement of water molecules only; requires a membrane but no energy.
osmosis
Monosaccarides are the building blocks of this major macromolecule
What are carbohydrates?
What happens during translation?
mRNA to protein
This is the site of protein synthesis.
What is the ribosome?
If you place a human blood cell in a cup of salt water, what will happen to it?
shrink
Name the building block of a protein.
amino acids
What does tRNA do?
bring amino acids
Only plants and some protists contain this organelle.
What is the chloroplast?
If there is more water outside a cell than inside and the cell begins to swell, is this a hypotonic or hypertonic situation?
hypotonic
