bio igcse2
enzymes
biological catalysts that speed up chemical reactions in living organisms without being used up
lock and key model
substrate: specific molecule enzyme acts on
Active Site: The region of enzyme substrate binds
Products: enzyme breaking down or building up substrate
change shape slightly to fit
enzyme inhibitors
block by competing or change it's shape
denaturation(when loses shape)
amylase
protease
lipase
catalase
substrate:hydrogen peroxide
product:H2O+O2
substrate:lipids(fats)
product:fatty acids+glycerol
substrate:protein
product:amino acids
substrate:starch
product:maltose
human nutrition
carbohydrates
proteins
lipids(fats n oils)
vitamin
minerals
water
fipre
helps digestion by moving through intestines
chemical reactions, transport, temp
help with functions
C=scurvy, D=rickets
energy storage, insulation
growth, repair
energy
mouth, esophagus, stomach, small intestines,pancreas, liver, gallbladder, large intestines, rectum
mechanical digestion
phisical breakdown(chewing)
chemical
breackdown with enzymes
egestion(feces)
ingestion (eat)
plant nutrition
Photosynthesis: green plants make own food with light energy. takes place in the chloroplast of plant cell
CO2+H2O ---light+clorophyll--> glucose(C6H12O6)+O2
light, CO2 concentration, temp
low supply of one limits process
