side-to-side. This side-to-side motion allows for the grinding and mastication of leaves and plants. Humans have the tooth and jaw structure which most closely resembles a herbivore - not a carnivore. The human mouth produces a salivary enzyme known as alpha-amylase. The sole purpose of this enzyme is to break down complex carbohydrates‚ which are found in plant foods‚ into simple sugars. There are no carbohydrates in meats‚ so a carnivore has no need for this enzyme - yet humans produce it

Concentration on the Activity of Amylase Title Influence of Concentration on the Activity of Amylase Abstract Does more or less concentration speed up the reaction rate of amylase in starch? In this experiment diluted solutions of amylase were created and then tested using a starch solution‚ I2KI for reaction times. The answer to the question was proved to be that more concentration of amylase speeds up the reaction time. Introduction The enzyme‚ amylase is found in the saliva of most

enzyme amylase. The amylase is used to break down the polysaccharide starch. Amylase is a digestive enzyme classified as a saccharidase (an enzyme that cleaves polysaccharides). It is mainly a constituent of pancreatic juice and saliva‚ needed for the breakdown of long-chain carbohydrates (such as starch) into smaller units. Amylase is also synthesized in the fruit of many plants during ripening‚ causing them to become sweeter‚ and also during the germination of cereal grains. Grain amylase is key
