Rennet (pron.: /ˈrɛnɨt/) is a complex of enzymes produced in any mammalian stomach‚ and is often used in the production of cheese. Rennet contains many enzymes‚ including a proteolytic enzyme (protease) that coagulates the milk‚ causing it to separate into solids (curds) and liquid (whey). They are also very important in the stomach of young mammals as they digest their mothers ’ milk. The active enzyme in rennet is called chymosin or rennin (EC 3.4.23.4) but there are also other important enzymes

metabolism. It is produced by photo-phosphorylation and cellular respiration and used by enzymes and structural proteins in many cellular processes‚ including active transport‚ respiration‚ and cell division. One molecule of ATP contains three phosphate groups‚ and it is produced by ATP synthase from inorganic phosphate and adenosine diphosphate (ADP). ATP is used is many organisms and also in different ways. Below are a few ways in which ATP is used. When muscles contract in any organism‚ it means muscle

In biological processes‚ the immediate energy source is often in the form adenosine triphosphate (ATP). The nucleotide ATP maintains both catabolic and anabolic reactions. An example of

* NCERT 1. Reproduction in Organisms INTRODUCTION Biology in essence is the story of life on earth. While individual organisms die without fail‚ species continue to live through millions of years unless threatened by natural or anthropogenic extinction. Reproduction becomes a vital process without which species cannot survive for long. Each individual leaves its progeny by asexual or sexual means. Sexual mode of reproduction enables creation of new variants‚ so that survival advantage is enhanced

Hydropower is a renewable energy source which is produced by the movement of water. The energy produced can be stored and utilized for various operations. By drawing inspiration from existing hydroelectric technologies‚ but implemented on a much smaller scale‚ we believe that enough energy can be produced to support disadvantaged communities in the wake of the recent tariff increase. As aspiring engineers‚ we are keen on using our creative problem solving skills to make a difference. In recent years

Marine Organism Introduction( By Elaine) Good morning‚ everyone. We are very honored to stand here to make this presentation. Firstly‚ I’d like to introduce our partners to you. This is our group leader Diao‚ and this is A‚ B‚ C‚ D‚ E. Today we are going to talk about the marine organism. Firstly let`s guess what it is ‚ok ‚let me tell you ‚it`s a kind of jellyfish‚and its name is Bougainvillia superciliaris. You may know that 71% of the earth is ocean‚ but you may not know how many

species win and others lose? Evolution has many different ways of making organisms all better‚ faster‚ and more adept to live. Four big categories of the mechanisms of evolution are natural selection‚ gene flow‚ genetic drift‚ and mutations. The majority of the time‚ nature goes by a trial and error system that can take up many centuries to come up with a change that is beneficial. Natural selection is the process in which nature removes its mistakes in the trial and error process. For example‚

Unicellular organism From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search "Single-celled" redirects here. For prison cell assignment‚ see Single-celling. Valonia ventricosa is among the largest unicellular species. A unicellular organism‚ also known as a single-celled organism‚ is an organism that consists of only one cell‚ unlike a multicellular organism that consists of multiple cells. Historically the simple single celled organisms have sometimes been referred to as monads

One major ways for the survival of all organisms is called adaptation. When it comes to Intertidal Organisms their no different. Intertidal Organisms inhabit the specific area between low tide and high tide next to the rocks on the coasts‚ marshes and or wetlands. Theses organisms can be from sea stars to types of algae and many more. As the tides come in‚ the habitat of intertidal organisms are sprayed with salt water. Then after the tide depletes‚ the habitat is exposed to the sun. It makes

antibiotics. For this reason‚ it is important to test and observe unknown organisms in the lab to continually improve the health and well being of society. The objective of this report was to first isolate a single colony of an unknown culture on a LB agar plate. From here‚ a slant was made and used for multiple types of testing in order to determine the identity of the unknown organism. The tests performed to identify the unknown organism included Gram Staining‚ Fluid thioglycollate/aero-tolerance test
