Macromolecules and Nutrition Labels
This macromolecule is the body's primary source of "quick energy.
Carbohydrates
Name the "Control Center" of the cell contains the genetic blueprints (DNA) in both eukaryotes and prokaryotes.
Nucleus (Eukaryotes) and Nucleoid (Prokaryotes)
What are the two types of feedback mechanisms we have?
Positive and negative
The movement of molecules from an area of high to low concentration.
Diffusion
Name the 4 macromolecules.
Carbohydrates, protein, lipids or fats, and nucleic acis
These small structures are the "Protein Factories" of the cell.
Ribosomes
Which feedback loop is normal, and which is more rare?
positive - rare
The specific term for the diffusion of water across a membrane.
Osmosis
This macromolecule provides long-term energy storage and makes up cell membranes.
Lipids or fats
This organelle acts like a "Powerhouse," converting glucose into ATP energy.
Mitochondria
Shivering when cold to generate heat is an example of this type of Feedback Loop.
Negative
What happens to a cell in a hypertonic solution?
Shrinks
This macromolecule helps the body repair itself, protect itself against diseases, and speeds up reactions.
Protein
These organelles contain digestive enzymes to break down waste (The "Garbage Men").
Lysosomes
This hormone is released to increase blood sugar.
Glucagon
Where does water want to move to: where there is more or less solutes?
Where there is more solutes
Name the function of nucleic acids.
That holds our genetic information.
What does the smooth endoplasmic reticulum make?
Contractions and oxytocin
Define solvent and solutes.
Solvent = usually water, liquid that is what dissolves the solute
Solute = solids that are dissolved
