Cellular transport of taurine is sodium dependant. The ratio of sodium molecules to taurine molecule transported varies in different tissues ranging from 3:1 to 1:1.Transport of taurine in brain require at least 3 Na+ molecules‚ transport of hypotaurine require 2 Na+ molecules. Transport of taurine takes place in both neurons and glial cells. The transport in glial cells is greater than neurons and astrocytes. Deficiency

ABSTRACT: This lab allows us to observe the conversion of hydrogen peroxide (H2O2) into water and oxygen gas. An enzyme known as catalase facilitates this decomposition reaction. The catalase enzyme acts as catalysis‚ helping lower the energy needed to activate the reaction while the enzyme itself is not affected. Catalase is a digestive enzyme used to break down hydrogen peroxide‚ which is a normal byproduct of cellular respiration. The reaction could take place without the help of catalase‚ but

AbstractThere were flaws in the experiment. With the measuring cups it was difficult to tell whether or not the estimation was correct. If the experiment were to be done again‚ it would have ice in the measuring cups to see how the cold would make any changes in the evaporation. The experiment was done because evaporation is something that is interesting to see what happens after the experiment is over. The experiment was done by making the water have different additives in it and seeing which one

Benjamin Kleveland 502 October 26‚ 2014 Lab 7 Report Lights Distance and Wavelength Effect on Photosynthesis Photosynthesis and cellular respiration are often mistaken as the same thing. Although they are similar in many ways‚ photosynthesis and cellular respiration are the exact opposite of each other. Not figuratively‚ but literally the reverse (Photosynthesis). They incorporate the others products while adding some outside energy to create a never ending cycle. This brings us to the photochemical

The different methods of measuring acids and bases in a solution By Starsky Intro to Biology September 26‚ 2011 Lab Partners: Kristen‚ Tania and Betty Introduction When using different methods to measure pH levels there are some tools that can be useful. Some more than others but by putting into action the different methods it may determine which tools will work best and give the best

couple of key things about lab safety and procedure during this experiment. While working with the hot plates‚ I learned to pay a lot of attention to whether or not the hot plate was plugged in or turned on‚ as well as whether or not the wax was getting too hot. Measuring each substance into the cup was an important experience because it taught me to be deliberate and careful when measuring so as to not waste materials‚ making sure we did not have to start over. While this lab is a good starting point

The properties of dibenzalacetone make it a great substance to be used when protecting the skin from the sun. In the experiment performed‚ dibenzalacetone was created from an aldol condensation of 2 portions of benzaldehyde and acetone in sodium hydroxide. The reaction that occurred in this experiment is known as a specific aldol condensation called Claisen-Schmidt. In the reaction‚ the carbonyl of benzaldehyde reacts quickly with the acetone anion to create a hydroxyketone that dehydrates in the

major habitat. They can be found over range of continents and have common characteristics with plants and animals. There are many types of Biomes on earth. BIomes are distinct from habitats‚ because any biome can comprise a variety of habitats. In our lab we had figure out the major components in a biome. For example‚ like the weather‚ what animals live in it‚ plant life‚ etc… And answer key questions to why something happens in a Biome. And how species and plant life depend on each other to survive

This experiment was conducted with two key biological principles in mind‚ taxis and kinesis. Taxis can be defined as a specific‚ directed motion in response to a stimulus‚ whereas kinesis is a random‚ undirected motion in response to a stimulus. The stimulus or independent variable in this experiment

Sample 1: Play ground sand: khaki colored‚ feels rough‚ has more sand than rocks. Sample 2: Potting soil: black/brown-ish colored‚ feels some what soft‚ has little pieces of bark (woody stem‚ branches‚ and roots of plants.) Sample 3: Backyard soil: Orange-red‚ feels lumpy‚ muddy look alike. What is the texture of each soil sample
