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
