Test 1 Flashcards
The number of neutrons does not equal the number of electrons and protons
Isotope
Name this: 2 neutrons, 3 protons, and 3 electrons
Isotope
When the number of electrons does not equal the number of protons and neutrons.
Ion
Example: 2 electrons, 3 protons, 3 neutrons
Ion
Ions always have electrical charge (T or F)
True
The number of hydrogen ions in a solution
PH
As you add H+ to a solution, the PH number goes (1) and the solution becomes more (2)?
1) down
2) acidic
They are very specific and sensitive to their environment, they speed up the reaction by lowering the activation energy
Enzymes
What are the parts of a membrane?
- Proteins
- Cholesterol
- Carbohydrates
- Phospholipid bilayer
This part of the membrane adds strength to the membrane
Cholesterol
These are used for cell recognition, an example is ABO blood typing
Carbohydrates chains
Part of the membrane that serve as channels and receptor sites
Protein
Make up the “skin” of the cell
Phospholipid bilayer
The head is hydro—? And the tail is hydro—?
Head= hydrophilic Tail= hydrophobic
Increase in the size of cells without division, the opposite of this is atrophy
Hypertrophy
Increase the number of cells due to an increase in cell division
Hyperplasia
What is an example of hyperplasia?
Cancer
What are the functions of SER?
- Produce testosterone
- Produce tri-glycerol in intestines
- Detox the liver
Bubble full of digestive enzymes?
Lysosomes
Produce most of the cell’s ATP
Mitochondria
