Biomolecules and Their Functions
This class of biomolecule codes for proteins and contains genetic information.
What are nucleic acids?
Amino Acid.
What is a Protein (polypeptide)?
Active transport requires this.
What is energy?
This is the direction molecules will flow in active transport.
What is high to low (with the concentration gradient)?
How many biomolecules ther are.
What is four?
This class of biomolecules often end in ose and can be used for energy or building cell walls.
What are carbohydrates?
A simple sugar/carbohydrate.
What is a monosaccharide?
This is the direction active transport moves molecules in.
What is low to high (against the concentration gradient)?
In a U-tube set up, one half of the tube contains pure water, and the other has water mixed with red dye. Over time, both sides appear a light red. Which type of transport is this?
Diffusion
What are stem cells?
This class of biomolecules are made up of amino acids.
What are proteins?
An important nucleic Acid.
What is a DNA?
This form of active transport moves molecules into the cell.
What is endocytosis?
A cell contains 30% water and the environment contains 50% water. What will happen to the cell and why?
The cell will swell due to osmosis.
These types of cells have a cell membrane but lack a nucleus.
Prokaryotes (bacteria).
This class of biomolecules is often hydrophobic and forms waxy layers such as those found on leaves of some trees.
What are lipids?
Made up of Fatty Acids
What is a lipid?
When molecules are too large to just go through the cell membrane
What is active transport?
A membrane filled with channel proteins is transporting salt. The salt moves from high to low concentration. Which type of passive transport is this?
Facilitated diffusion
This is the process that turns sugar into ATP energy.
What is cellular respiration?
This class of biomolecules includes the catalysts for chemical reactions.
What are enzymes?
Polymers and strung together by bonding many of these subunits together.
What are monomers?
This kind of active transport is also called "cell drinking."
What is pinocytosis?
A red blood cell contains 20% salt and the environment contains 40% salt. What will happen to the red blood cell over time?
It will shrink due to osmosis.
This is a very large and long carbohydrate.
What is a polysaccharide?
