Energy for Life 3.3

metabolism the total of all chemcial reactions in an organism
enzymes protein that allow chemical reactions in cells to happen
do enzynmes change? no
can enzymes be reused? yes
how do enzymes change large molecules? name 2 steps. they attach to the large molecule it will help change. the enzyme causes the larger molecule to break down into 2 smaller molecules.
organism anything that is living
what are the 2 groups of organisms, based on hol they get thier food? producers - plants; consumers - do not make thier own food
photosynthesis the process by which producers use light energy to make sugars which can be used as food. sunlight energy is changed into chemical energy
what is the green pigmant in a producer? Chlorophyl
where is the ngreen pigment in a producer found? chloroplast
what is the function of the green pigment in a producer? to capture sunlight
what does photosynthesis begin with? what raw materiels? CO2 and H2O
what is CO2? carbon dioxide
what is H2O? water
what is propduced by 6 molecules of carbon dioxide + 6 molecules water + light energy? 1 molecules sugar + 6 molecules oxygen
what is C6H12O6? molecules of sugar (carbohydrate)
what is 6O2? 6 molecules of oxygen.
what is extra sugar stored as in a plant? starch
what do plants use carbohydrates as? food - to grow, maintain, reproduce
how is photsynthesis involved in things you eat? indirectly and directly
respiration a series of checmical reactions in producers and consumers that break down food molecules into simpler substances and release thier stored energy.
name 2 things your body uses the engergy produced by respiration for? for your muscles and other body cells for thermal (heat) energy
what is the type of food most easily broken down by cells? carbohydrates
where does the respiration of carbohydrates begin? in the cytoplasm
what is the carbohydrate broken down into in the cytoplasm? glucose molecules and then into 2 simplier molecules
where arte these 2 simplier molecules broken down again? in the mitochondria
what does this process (respiration) of breaking down carbohydrates and then glucose use and produce? uses oxygen releases energy produces CO2 and H2O as waste
fermentation a process by which oxygen-lacking cells and some one-celled organisms release small amounts of energy from glucose molecules
what is produced as waste by fermentation? alcohol, CO2, and Lactic Acid
where does fermentation occur? occurs in cytoplasm, but does not move to the mitochondria
Name 4 foods or other things that bacteria can make through fermentation and the production of lactic acid. yogurt, some cheese, solid milk, food flavors
name a one-celled organism that uses fermentation to break down the sugar in dough yeast
what waste does yeast produce in the fermneation of sugar in dough? CO2, alcohol
respiration uses......... sugars and oxygen
respiration produces........... CO2 and H2O
photosynthesis uses.......... CO2 and H2O
photosynthesis produces........... sugars and oxygen
