APHY 101 IVY TECH EVALUATION EXAM 2026 QUESTIONS
AND SOLUTIONS SCORED A+
✔✔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 - ✔✔separation of two macromolecules by adding water. Releases
energy
✔✔what are carbohydrates - ✔✔provide energy and cell structure
✔✔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? - ✔✔a substance produced by a living organism that acts as a
catalyst to bring about a specific biochemical reaction.
✔✔DNA - ✔✔Part of chromosomes and in nucleus. responsible for storing and
transferring genetic information.
✔✔RNA - ✔✔located in cytoplasm. directly codes for amino acids and as acts as a
messenger between DNA and ribosomes to make proteins
✔✔describe cell membrane - ✔✔controls what goes in and out of cell, phospholipid
bilayer
✔✔nucleus - ✔✔control center
✔✔cytoplasm - ✔✔contains cytosol
✔✔cytosol - ✔✔aqueous substance
, ✔✔organelles - ✔✔organized/specialized structures in cell
✔✔Function of Ribosomes - ✔✔synthesize protein
✔✔ER - ✔✔transport system, ribosome attachment, synthesize lipids
✔✔Golgi apparatus - ✔✔modify, package, deliver protein
✔✔mitochondria - ✔✔generate energy
✔✔Function lysosome - ✔✔digest worn out cell parts or unwanted substances
✔✔peroxisome - ✔✔breakdown organic molecules
✔✔centrosome - ✔✔produce cilia and flagella, distribute chromosomes during cell
division
✔✔Function vesicle - ✔✔store, transport or digest cellular products and cellular waste
✔✔cilia - ✔✔propel substances across surfaces
✔✔flagella - ✔✔motility of sperm
✔✔function of nuclear envelope - ✔✔control substance in and out of nucleus
✔✔nuclear pores - ✔✔a large complex of proteins that allows small molecules and ions
to freely pass, or diffuse, into or out of the nucleus
✔✔nucleolus - ✔✔site of ribosome formation
✔✔chromatin - ✔✔package DNA into a small volume to fit into the nucleus of a cell and
protect the DNA structure and sequence
✔✔define pinocytosis - ✔✔engulfs liquids from surrondings
✔✔define phagocytosis - ✔✔engulfs solids from surroundings
✔✔exocytosis - ✔✔vesicle fuses with membrane and releases contents outside of cell
✔✔transcytosis - ✔✔ferries particles through cell
✔✔isotonic - ✔✔neutral
