Anatomy & Physiology Exam Review Ivy
Tech APHY 101 Exam 1 2 AND 3 Questions
and answers 2025
Cellular & Molecular Biology
Signs of aging at the cellular level:
✔✔ Impaired cell division and reduced ability to recycle worn cell parts.
Three major parts of a cell:
✔✔ Nucleus, cytoplasm, and cell membrane
Smooth ER vs Rough ER:
✔✔ False — Smooth ER does not have ribosomes; rough ER does
Organic compounds always contain:
✔✔ Carbon and hydrogen
Lipids:
✔✔ All of the above (nonpolar, energy storage, component of membranes)
Electrolyte ionizes in water:
✔✔ True
,An element:
✔✔ Iron
Group of compounds that is hydrophobic:
✔✔ Carbohydrates (Note: this is incorrect scientifically; the correct answer
should be "lipids")
Elements that account for 95% of the human body:
✔✔ Carbon, hydrogen, oxygen, nitrogen
Atoms of isotopes vary in number of:
✔✔ Neutrons
Chemistry in Physiology
Chemistry is important to physiology because:
✔✔ All of the above
Decomposition reaction:
✔✔ AB → A + B
pH of acids:
✔✔ Vinegar, grapes, tomatoes, coffee
,Difference in H+ concentration between pH 4 and pH 5:
✔✔ Tenfold
Neutral solution:
✔✔ Equal numbers of H⁺ and OH⁻ ions
Symbol Na⁺:
✔✔ True — sodium atom has lost an electron
ATP importance:
✔✔ Provides energy for cellular work
Cell Transport & Homeostasis
Transport that does NOT require energy:
✔✔ Facilitated diffusion
Simple and facilitated diffusion both:
✔✔ Move substances down a concentration gradient without energy
Water leaves a cell in a:
✔✔ Hypertonic solution
Selectively permeable membrane:
✔✔ Allows some substances, blocks others
, In phagocytosis:
✔✔ Cell engulfs solid particles
Negative feedback:
✔✔ Stimulates change in opposite direction from deviation
Homeostasis:
✔✔ Body’s tendency to maintain stable internal environment
Cellular Respiration & Metabolism
Metabolism:
✔✔ All chemical reactions that support life
Catabolism vs Anabolism:
✔✔ False — Catabolism breaks down; anabolism builds up
Example of catabolism:
✔✔ Breakdown of glucose
Glycolysis:
✔✔ Breaks glucose into pyruvic acid
Aerobic reactions location:
