carbon hydrogen oxygen nitrogen (CHON)

All proteins contain...

fifty amino acid units

Each protein molecule is made of at least ______________.

-iron -sulfur -phosphorus -zinc -nitrogen

Elements in protein

proteins

Enzymes are...

-solar energy -storage of energy -release of O2 -ATP

List the associations of the "light phase" of photosynthesis

-CO2 intake -release of energy -release of water -forms carbohydrates

List the associations of the dark phase of photosynthesis

ribosomes in plants and animals

Proteins are made by...

both plant and animal cells

Ribosomes are found in...

produce a carbohydrate from CO2

The chemical energy stored in ATP during photosynthesis is released during the dark phase to:

Carbon dioxide

_______ levels above normal will increase plant growth if other factors are adequate.

protein

a food made up of carbon, hydrogen, oxygen, nitrogen

carbon dioxide fixation (dark reaction)

carbon as an atmospheric gas is locked into a food molecule (+ where does this take place?)

Van Niel

claimed that oxygen produced by photosynthesis comes from the splitting of the water molecule

oxygen

essential to aerobic respiration

green house

may be used to control temperature and CO2

fat

provides energy storage and structure for life

amino acids

the building blocks of proteins

ATP

the high energy chemical compound that provides energy

splitting of water molecules

the oxygen which is released into the air by a plant originates from...

protein synthesis

the putting together of protein molecules from amino acids

stomate

the tiny pores or leaf openings appearing between guard cells

thousands of different proteins

twenty-two amino acids are capable of producing...

Robert Hill

worked out reactions taking place during the light reaction
