Roy Levin Bio 11 Lab Dr.Izquierdo Analysis of Macromolecules in Tissue Homogenates of Bos taurusMaterials and Methods The homogenates provided were made by homogenizing tissues in a sucrose phosphate buffer in a 1:20 ratio. The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to

and potassium are three very essential nutrients that collectively aid in photosynthesis‚ growth‚ formation of proteins‚ and overall quality of the plants. Not having these essential nutrients may result in various diseases‚ leaf discoloration‚ and very limited growth. In our experiment we decided to test how exposure to sunlight (or lack thereof)‚ and the amount of nutrients available to plants affect seed germination as well as overall plant growth. We did this by exposing some plants to light while others not‚ and by applying the synthetic

Introduction In unit 7.3 the experiment tested the ability of lactase to specifically bind and interact with lactose compared to maltose. In unit 7.4 the experiment tested the role‚ if any‚ that metal ions have on the activity of lactase. My hypothesis for unit 7.3 was knowing that lactase is specific for lactose‚ lactose will separate into galactose and glucose‚ as maltose will not change (153-155). Lactase should like lactose. For unit 7.4 my hypothesis was that EDTA will remove the ions‚ and
