    Chemistry of cosmetics Few people would whip out a chemistry set‚ uncork the vials‚ and slap the compounds on their face. Yet‚ millions of women and girls essentially do that every day when they unzip their makeup bags and apply lipstick‚ mascara‚ and other makeup. Like the compounds in a chemistry set‚ makeup consists of chemicals. Although the chemicals in cosmetic products are intended to improve the appearance of skin‚ lips‚ and lashes‚ some can cause adverse effects. Emulsions The majority

    both germinating pea seeds and crickets. 3. Perform an investigative study of the rate of cellular respiration in both pea seeds and crickets at various temperatures. 4. Compare the alcoholic fermentation of glucose‚ sucrose‚ and starch by yeast. Introduction All organisms must have a continual supply of external energy in order to maintain bodily functions and to combat entropy. Ultimately this source of energy is the sun. As you learned in the previous lab‚ plants can convert the

    actually hinder the enzymatic reaction. My reasoning behind this is that the substrate will take a longer time to mix with the fluid acids‚ and thus much of the time will be wasted when the enzyme makes contact with the combined substances. Design: In order to do this‚ we will be using the following materials: Yeast Packet (this will be our enzyme‚ which comes from (source))‚ 30 mL 3% Hydrogen Peroxide (this will be our substrate)‚ (2) 250 mL Beakers‚ 3 Balloons‚ H 2 O 2‚ Measuring Spoon‚ Permanent

    respiration in yeast/onion cells. * Measure respiration rate using different substrates. * Measure respiration rate at different temperature. Introduction: In this laboratory experiment‚ we are given 3 task. The first one is respiration in yeast. Second is respiratory indicator and the third one is observing mitochondria in yeast/onion cell. The first experiment is about investigation of sugars yeast. We will determine which sugars yeast can be use for cell respiration. When the yeast undergoes

    would take an extremely long time to happen. In order to catalyze reactions‚ the substrate‚ the reactant the enzyme performs on‚ must first bind to a specific area on the enzyme called the active site. It is currently believed that there are several different methods in which an enzyme lowers the activation energy of a reaction and therefore speeds up the process. To begin with‚ by binding with the substrates‚ the enzyme is able to bring the different reactions closer together‚ making it easier
