Chemistry Of Life Flashcards
Water
Most abundant substance in living cells, approximately 60% to 80% plasma
Carbon dioxide
Waste product of cellular respiration & must be eliminated quickly from the body through expiration via respiratory system & cardiovascular system
Molecular oxygen
Required by all organisms that breathe air, necessary to convert chemicals energy(food)
Ammonia
Contains nitrogen which is the essential element in amino acids(building blocks of protein)
Mineral salts
Needed for body, essential for survival and functioning of body’s cells
Carbohydrates
Quick source of energy
Lipids
Long term source of energy, insulator to prevent heat loss
Protein
Provide structural support, transport substance through the body ,catalyst during metabolism
Nucleic acids
Genetic material in the body
Adenosine triphosphate
High energy molecule/ fuel that runs the cell’s machinery
