15 Cards in this Set

  • Front
  • Back
enzymes are protein catalysts that decrease the energy of activation needed to begin a reaction
competitive inhibitor competes with the substrate for the active site
non competitive alters an enzymes function by changing it's shape
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
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
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
