four major chemical organic compounds in all living things
Four major chemical/organic compounds in all living things
  • 1.carbohydrates
  • 2.lipids
  • 3.proteins
  • 4.nucleic acids
cell biology molecular biology
Cell Biology (molecular biology)
  • What are the basic building blocks of life?
  • Functions:
    • 1. DNA: deoxyribonucleic acid – genetic instructions, usually double
    • 2. RNA: ribonucleic acid – genetic instructions, single stranded
protein synthesis
Protein Synthesis
  • Transcription:

Occurs in nucleus writes DNA to RNA

  • Translation:
  • Occurs outside the nucleus and transcribes the mRNA to tRNA & codons (proteins)

Components & Functions

  • Components & Functions
temperature conversions
Temperature Conversions
  • [°C] = ([°F] - 32) × 5/9
  • [°F] = [°C] × 9/5 + 32
  • Kelvin = [°C] + 273
mitosis vs meiosis
Mitosis vs. Meiosis
  • Mitosis/Meiosis

life span of cells
Life Span of cells
  • Bacteria
  • Red blood cells
  • Stem cells
  • Bacteria spore

Level of Hierarchy in organisms
  • Cell
  • Tissue
  • Organ
  • Organ system
  • organism
1 muscular system
1. Muscular System
  • Function:

MOVEMENT!

  • Voluntary: arms move
  • Involuntary: stomach, heart
  • Skeletal: help body to move
  • Smooth: help organs move
  • Cardiac: heart
skeletal system
Skeletal System
  • Function: Support, movement, protects organs
  • Bones:
  • Ligaments
  • Tendons
nervous system
Nervous System
  • Sends messages throughout body
  • CNS: Brain and spinal cord
  • PNS: nerves that go off the CNS
5 senses
5 senses
  • Sight
  • Hearing
  • Touch
  • Taste
  • Smell
endocrine system
Endocrine System
  • Sends messages throughout the body
  • Organs: kidney, pancreas, brain
  • Glands: release hormones (Thyroid gland, pituitary gland)
  • Hormones: chemicals that send messages, triggers changes (growth, metabolism) (HGH)
circulatory system
Circulatory System
  • Body’s transport system: blood, hormones, O2
  • Heart: pumps blood
  • Veins, arteries, capillaries
  • lungs
lymphatic system
Lymphatic System
  • Defense system
  • Lymph nodes
  • White blood cells
respiratory system
Respiratory System
  • Exchanges O2 and CO2
  • nose
  • Trachea
  • Bronchial tubes
  • Lungs
  • Alveoli sacs
digestive system
Digestive System
  • Breaks down food for energy
  • Mouth and saliva (chewing)
  • Esophagus
  • Stomach (breaks down food with acids)
  • Intestines (absorption)
  • Anus (waste)
urinary system
Urinary System
  • Eliminate toxins and wastes
  • Kidneys (filter)
  • Ureters (transport)
  • Urinary bladder
  • Urethra (gets rid of waste)
reproductive system
Reproductive System
  • Allows humans to reproduce
  • Male: Sperm, testes
  • Female: egg (ovum), uterus
  • Lots of hormones involved with this system (testosterone, estrogen…)
integumentary system
Integumentary System
  • Protection
  • Skin – largest organ
teeth
Teeth
  • Chewing, speaking, health – 32 teeth total
  • 2 sets of teeth:
    • 1.
    • 2.
  • Types of Teeth
  • Incisors: 8
  • Canines/cuspids: 4
  • Premolars: 8
  • Molars: 8
  • Third Molars: 4*
vitamins nutrients
Vitamins & Nutrients
  • ______________: when the body cannot synthesize enough of the nutrient that it requires it from its diet
  • ______________: come from the earth
  • Classified for what they do
  • Vitamin A/carotenoids: vision, bone growth, repro, cell division, immune system (liver, beef, milk, carrots, spinach)
  • Vitamin B2/riboflavin: body growth, repro, RBC
  • Vitamin B6: metabolism, catalyst & rxns, energy (beef, liver, starches, fruit (not citrus)
  • Vitamin B12:required for RBC formation, neuron formation and DNA synthesis(fish, meat, poultry, eggs, milk)
  • Folic Acid (B9 vitamin): growth
  • Vitamin C: antioxidant, antiviral agent (citrus, broccoli, chestnuts
  • Vitamin D: calcium absorption, bone growth/strength (comes from the sun and some foods – fish and some dairy)
  • Vitamin E: antioxidant, fat decomposition, immune (nuts, seeds, oils, leafy greens)
  • Vitamin K: Blood clotting, regulates blood calcium levels (avocado, berries, greens, nuts)

antibiotics
AntiBiotics
  • Anti/bios: against/life
  • Drugs to treat infections caused by ______________
  • TB
  • Penicillin
  • Kills bacteria and stops them from multiplying
  • Not effective with ______________.
ecosystem
Ecosystem
  • Biotic and abiotic (living and non living) that make up a biological environment
food chain
Food Chain
  • Food Chain
sym biotic relationships
Sym/biotic Relationships
  • Mutualism: both members mutually benefit
  • Commensalism: one benefits while the other is unaffected
  • Parasitism: one benefits at the expense of the other (host)
  • symbiotic examples
