The Body Balance
All living things must maintain this in order to stay alive
Homeostasis
All the chemical processes used to maintain homeostasis are called what.
metabolism
water
Organic compounds always contain these 2 elements. Name 1
Carbon and Hydrogen
A starch is broken down by ____________ into 2 simple sugars
enzymes
Failure to maintain Homeostasis may result in _____ or ____.
Using nutrients for growth, synthesis , repair and energy is which life process
Nutrition
This is needed by MOST organisms for cellular respiration.
Oxygen
These are sugars and starches
Carbohydrates
What are 2 functions of lipids
store energy
protect cell membrane
water proofing
insulation
Homeostasis is often maintained by this type of mechanism
Feedback
Converts energy in food into a usable form of ATP
Cellular respiration
This is used by plants along with sunlight and water to make glucose. It is also a waste product of aerobic respiration.
Carbon Dioxide
Fats, oils and waxes are which organic compound
Lipids
What are the functions of carbohydrates
to provide and store energy
What is a feedback mechanism and give an example.
Feedback mechanisms are cycles in which the product of one reaction causes another to start or stop.
Example: Hot, sweat, cool down, stop
Absorbing and distributing materials throughout the body is which life process.
Transport
This is the most common gas in air. It is also used to make protein and is excreted as waste in ammonia or urea.
Nitrogen
What are the building blocks of proteins
Amino Acids
What are the building blocks of nucleic acids
Nucleotides (phosphate, sugar, bases); molecular bases (ATCGU)
While organisms are balanced, they are not unchanging. What is the term used to describe this balanced state
Dynamic equilibrium
Removing wastes produced by metabolic activities is which life process
Excretion
These two are measured by the pH scale. Very high and very low pHs are usually lethal. They can also affect rates of chemical reactions; for example, digestive enzymes work fastest in one of these types of environments.
acids and bases
This compound make up genes and chromosomes
Nucleic acids
Name 2 important types of proteins
Hormones and neurotransmitters
cell receptors
Antibodies
Enzymes
