APHY 101 - Anatomy and Physiology I
APHY 101 Final Exam Latest 2025/2026 Ivy
Tech Community Complete Question and
Answer Graded A
What is the difference between anatomy and physiology
anatomy- study of structure
physiology- study of function
what happens to salts when dissolved in water and what is produced?
The salt molecules are "torn apart" by the water, and are reduced to sodium (Na+) and chlorine (Cl-)
ions.
what is the pH scale? what ions are involved in the pH scale?
pH scale- indicated the concentration of hydrogen ions in a solution, H+ and OH-
organic molecule
contains Carbon and hydrogen and dissolves in water.
inorganic molecule
does not contain C and H and dissociates with water
What is dehydration synthesis
taking water out (producing water) to form a new product. Uses energy
hydrolysis

APHY 101 - Anatomy and Physiology I
separation of two macromolecules by adding water. Releases energy
what are carbohydrates
provide energy and cell structure
what is a homeostatic mechanism
monitors aspects of internal environment and corrects as needed
*negative feedback mechanism
define matter
anything that takes up space and has mass
element
composed of chemically identical atoms
atom
smallest particle of atom, basic unit of matter
what are structure of an atom
nucleus
protons
neutron
electrons
define nucleus, proton, electron, neutron
nucleus- central part of atom
proton- positive charge
electron- negative charge
neutron- no electrical charge
ionic bond
formed when electrons are transferred from one atom to another
what are covalent bonds
when two molecules share electron

APHY 101 - Anatomy and Physiology I
hydrogen bond
formed between water molecule, attraction between positive end of polar molecule and negative end of
another polar molecule
define synthesis, decomposition, and exchange reactions
Synthesis- A+B=AB
Decomposition- AB=A+B
exchange- AB+CD=AD+BC
define reactant
starting materials of reactions
product
ending material
define catalyst
a substance that speeds up a chemical reaction
what is an acid
dissociates with water
base
combines in water
lipids
provide energy and cell structure
proteins
structural material, enzymes, energy, hormones,
nucleic acids
store information for protein synthesis, control cell activity
what are amino acids?
Protein building blocks which are help together by peptide bonds
what are enzymes?
