microscopic cellular organisms and their structures
physical structures of all organisms
interactions of millions of organisms with other species and their enviroment
What does biology include the study of
100
carrying materials where they need to go in an organism ex. circulatory system.
What is Transport
200
Carbohydrates, proteins, lipids, and Nucleic acids
What are Categories of Polymers in living things
200
Made up of glycerol(3 carbon molecule) and 3 fatty acids(long hydrocarbon chain)
What is a Lipid
200
breaking down of proteins due to unfavorable pH, temp, etc. The protein doesn't function properly anymore
What is denaturation
200
-biological systems- parts of organisms or enviroment working together
-cells are the basic unit of all living things
-All structures are formed in a specific way
-organisms must reproduce to pass on traits to future generations
-All organisms interact continoulsy with their environment
-Living things must obtain and use energy to perform life functions
-organisms regulate their internal condions
-living things continue to adapt and evolve to their changing enviroment
-Biology constantly affects our daily lives
-scientists are always "inquiring" about why things happen the way they do
What is the Ten Major Themes of Biology
200
Getting oxygen to cells to help break down nutrients to make energy (ATP) ex. oxygen and glucose= CO2+H2O+Energy
What is Respiration
300
organic compound made up of Sugar molecules that contain the elements of hydrogen and oxygen in a 2:1 ratio
What are carbohydrates
300
Saturated- solids at a room temperature. ex. butter
Unsaturated- liquids at room temperature ex. oils
Fats provide stored energy for later use and also insulation for your body
What are types of fats
300
make enzymes
make receptor molecules on cell membranes to recieve chemical messages
make antibodies
make hormones
make up hair, skin, nails, and muscles
What are specific jobs of proteins
300
-are composed of cells
-obtain energy and use it to carry out metabolic activites
-must respond to the environment and maintain homeostasis
-Must grow and develop increase in size, form new structures
- Have the ability to reproduce(sexually or asexually)
-must be able top adapt and evolve (natural selection)
What is the Characteristics of living things
300
combining smaller molecules to form larger more complex substances ex. making a protein, repairing a bone
What is Synthesis
400
basic unit of carbohydrates; simple sugars used as a first source of energy ex. glucose, fructose, galatose
What is Monosaccharide
400
type of lipid with a ring structure ex. cholesterol, testosterone, estrogen
What are steriods
400
DNA & RNA
function in controlling organism traits
What are nucleic acids
400
Breaking down materials from the external environment into a usable form by cells to make energy ex. digestive system
monomers of proteins, building blocks of protein, there are 20 different of these
What are amino acids
500
are catalysts that help speed up chemical reactions in organisms
"Lock and Key" model- each of them works with one particular reactant molecule that fits into a key on a lock
substrate- the reactant molecule
active where substrate attaches to the enzyme
Changes in TEMPERATURE AND PH can cause it to denauture and not function
What is an enzyme
500
increase in size (number of cells) and specialization of cells
What is growth and development
500
Maintaing homeostasis ex. nervous system, endocrine system (hormones)
