  • most biomolecules are organic
  • polymers are made up of monomers sub unit
  • carbohydrates - source or energy and structure. Means hydrated.
  • chitin - major component of exoskeleton; hard shells like crabs and scorpions
  • waxes - waterproof, resistant to degration
  • steroids - cell messengers (ex. cholesterol and hormones)
  • phospholipids - cell membrane component
  • Dna - deoxyribonucleic acid, stores & transmits information used to assemble proteins
  • RNA - ribonucleic acid, reads DNA-encoded information to direct protein synthesis. Three types: messenger, ribosome, and transfer RNA
  • collagen - type of structural protein that makes up our skin
  • keratin - structural protein that is found in our nails and hair.
  • there are 20 amino acids but only 12 are essential.
  • structural protein - type of protein used for collagen and keratin
  • defense protein - type of protein used for the defensive mechanism of our body
  • transport protein - type of protein used for transporting oxygen
  • secretory protein - type of protein used for metabolism
  • organ systems - biological systems consisting a group of organs
  • anatomy - parts, physiology - function
  • digestive system - used for digestion & elimination process. (moth, esophagus, stomach, liver, intestine, pancreas)
  • circulatory - used for transpoting blood & oxygen (heart, blood, blood vessels)
  • respiratory - used for gas exchange for breathing (nose, pharynx, larynx, trachea)
  • excretory - used for removing waste in our body (kidney, unary bladder, urethra)
  • endocrine - regulates body’s metabolic activities (pancreas, thyroid, ovary)
  • nervous - gives commands to our body (brain, spinal cord, nerves)
  • muscular - movement (cardiac, skeletal, smooth muscle)
  • skeletal - structural support (bones, ligaments, cartilage, tendons)
  • integumentary - protection, skin, temperature regulation (skin, hair, nails)
  • immune & lymphatic system - primary defense against pathogens (tonsils, lymph, spleen)
  • reproductive - fertilization and reproduction (ovary, uterus, vagina, testis, penis)
  • homeostasis - helps maintain our internal conditions while dealing with the external environment. Maintains equilibrium.
  • Hypothalamus - located above the brain stem, acts as our body’s smart control coordinating system.
  • examples that ay disrupt homeostasis - increase in body temperature, blood sugar level, blood pressure
  • 3 components that regulate homeostasis - sensor or receptor, control center, effector
  • sensor or receptor (nervous system) - receives stimuli if there are changes in the environment.
  • control center (brain) - gives signal to the effector
  • effector - decides the response
  • negative feedback - important to regulate homeostasis and stops the response
  • positive feedback - increases the response continuously.
  • hormones - travels though the blood stream, can either be proteins or lipids.
  • endocrine ccells - produces hormones
