signal molecules to receptor proteins and heart muscles. Changes in permeability Occur when a receptor protein is coupled with an ion channel. Functions of receptor proteins The signal molecule binds to the receptor protein that’s specialized to fit the molecule. Binding of a signal molecule to the matching receptor protein causes a change in the activity of the receiving cell in three ways: 1. Changes in permeability of receiving cell 2. Triggering the formation of second messengers inside

three main textures: clay‚ sand‚ and silt‚ all of which can be determined through their porosity or permeability. Porosity is the measure of space between soil particles. If spaces are completely compacted‚ no water and air can be store and there would be zero porosity. Permeability‚ on the other hand‚ is water and air’s ability to move through the soil. Larger sized particles means more permeability and fast movement. Finding out the texture of soil is important in that it determines what vegetation

BALANCE We produce acetaldehyde by dehydrogenation of ethanol. Flow chart is as shown in the figure. Reaction: C2H5OH Catalyst: Æ CH3CHO + H2 Cu -Co-Cr2o3 Temperature: 280 – 3500 C. Process description: The raw material i.e.‚ ethanol is vaporized and the vapors‚ so generated‚ are heated in a heat exchanger to the reaction temperature by hot product stream. The product stream is cooled to –100 C and in doing it‚ all unreacted ethanol and acetaldehyde are condensed. The out going gaseous

guajava) Peeling as a Potential Source of Ethanol ABSTRACT Apple guavas are abundant in the Phillipines and have been known for their high nutritional value and herbal properties. The peeling of the fruit Psidium guajava is known to contain a significant amount of glucose‚ a simple sugar which is essential in the fermentation process in ethanol making. The study was conducted to determine the effectiveness of apple guava peelings as a potential source of ethanol. The peelings underwent many processes

Hemoglobin and its importance Oxygen is the most essential element required to sustain human life. If an adequate supply of oxygen is not circulated throughout the body to vital organs and tissues‚ brain damage‚ organ failure and death can result. Hemoglobin (Hb)‚ the iron-containing respiratory protein in red blood cells‚ is responsible for transporting oxygen from the lungs to the rest of the body. Measured in grams per deciliter (g/dL)‚ hemoglobin levels indicate the blood’s ability to carry
