ENZYMES
|
enzymes are protein catalysts that decrease the energy of activation needed to begin a reaction
|
|
|
INHIBITORS
|
competitive inhibitor competes with the substrate for the active site
non competitive alters an enzymes function by changing it's shape |
|
|
ACTIVE TRANSPORT
|
Transport proteins can move solutes against a concentration gradient
|
|
|
summary equation for cellular respiration
|
glucose + oxygen gas >>>>
carbon dioxide + water + atp |
|
|
what provides energy for life?
|
photosynthesis and cellular respiration provide energy for life
|
|
|
purpose for breathing
|
supplies oxygen to our cells and removes carbon dioxide
|
|
|
3 stages of cellular respiration
|
1-glycolysis
2-citric acid cycle 3-oxidative phosphorylation |
|
|
1st stage cellular respiration
|
1st stage is glycolysis is when the glucose is broken down into 2 molecules
|
|
|
2nd stage cellular respiration
|
main purpose is to supply the 3rd stage of respiration with electrons
|
|
|
3rd stage cellular respiration
|
3rd stage is Oxidative Phosphorylation- ATP synthesis and production
|
|
|
FERMENTATION
|
an anaerobic alternative to cellular respiration
lactic acid -cheese and yogurt alcohol fermentation-brew , beer and alcohol |
|
|
where does photo synthesis occure ?
|
in the chloroplasts
|
|
|
photosynthesis occurs in two stages
|
1-light reactions- the steps that absorb solar energy and convert to chemical energy
2-calvin cycle-produces sugar, occurs in the stroma of the chloroplast |
|
|
photosynthesis uses _____ to make food molecules
|
uses light energy to make food molecules
|
|
|
stromata, thylaloids and stroma
|
carbon dioxide enters the leaf,oxygen exits by means of the stromata. sugars are made from CO2 and water , the sugars are stores in the thlakoids
