Biology 1 year 9

• To test for protein you use biuret Solution, if it goes purple it’s positive
• the function of the pancreas is produce insulin
• To test for complex sugars you use iodine, if it’s positive the solution would go blue/black
• To test for simple sugars you use Benedicts solution, if it is positive it would go green, orange or red
• To test for lipids you use ethanol that is activated by water, if it is positive it goes cloudy
• The 4 basic/ major types of tissues in the human body are epithelial, muscle, glandular and nerve
• In the stomach, there is glandular, inner epithelial, outer epithelial and muscular tissue
• Organ systems include nervous, immune, reproductive, respiratory, digestive, muscular, cardio/vascular, urinary.
• Proteins are used for growth and repair
• Enzymes are a type of catalyst.
• Enzymes have to be specific
• Proteins are produced by ribosomes
• The unique part of the enzyme where the substrate binds is called the active site.
• 37 degrees the the common optimum temperature for enzymes
• Most enzymes work best at PH 7
• When an enzyme denatures the bonds break in the enzymes active site so the active site changes shape so the substrate can no longer bind
• Rate of reaction is 1000/time
