out of the cell‚ while preventing the passage of ions and other solutes. Also known as water channels‚ aquaporins are integral membrane pore proteins. Some of them‚ known as aquaglyceroporins‚ also transport other small uncharged solutes‚ such as glycerol‚ CO2‚ ammonia and urea across the membrane‚ depending on the size of the pore. For example‚ the aquaporin 3 channel has a pore width of 8-10 Ångströms and allows the passage of hydrophilic molecules ranging between 150-200 Da. However‚ the water

Evolution of Life The earth is about 4.54 billion years old and it is evolving throughout its lifetime from a place with volcanoes‚ serve thunderstorms and limited oxygen. The beginning of the life of earth is occurred due to a process that has set a sequence most practical events towards the foundation of where life actually formed so many years ago. The chemical evolution practical process created inorganic molecules to form organic molecules. Slowly this process of evolution created the foundation

Part C Digestion is the procedure of breaking down food into smaller parts. Most of the food humans consume should be digested into more basic parts‚ in order for it to be absorbed into the body and used within the body. Additionally‚ nutrients are the most important substances that allow the body to perform daily activities. Furthermore‚ carbohydrates‚ fats and proteins are the chief nutrients that the human body needs‚ in order to grow‚ repair‚ move‚ and maintain homeostasis. These nutrients

Human Physiology Spring 2014 Exam I 1. If red blood cells are placed in a hyperosmotic solution they will: a. shrink b. swell c. can’t tell what the cell will do d. remain the same 2. If red blood cells are placed in a solution that is hypotonic the cells will: a. shrink b. swell c. remain the same d. change depends on type of solutes 3. Using the information presented in lecture which of the following is most likely to be the source for the keto acid necessary for the production

Effect of Varying Temperatures: The enzyme catalyzed reaction rate during varying incubation temperatures are plotted on Figure. 6. As the temperature increases the rate increases‚ but as the temperature reaches 49oC it begins to drop. When the plot of the logarithm of the rate is used against the inverse of the temperature kelvin’s the Arrhenius equation is used to calculate the activation energy. The range in orange is between 16.5 - 37oC and the activation energy is calculated to be 9332kcal/mol

Carbohydrates have two major functions in plants and animals: they serve as fuel and building material. Plants store most of their energy in the form of starch. Starch is a polysaccharide (consisting of several conjoined sugars). Synthesizing starch enables the plant to stockpile surplus glucose‚ and since glucose is a major cellular fuel‚ starch represents stored energy. The sugar can later be withdrawn by hydrolysis‚ which breaks the bonds between monomers. Animals‚ in turn‚ have enzymes that
