Movement of solute molecules across the cell membrane into regions of higher concentrations or against a concentration gradient, with the use of metabolic energy input is known as active transport. Binding protein transport systems or ATP-binding cassette transporters (ABC transporters) is a good example of...
Respiration is the chemical process by which organic compounds release energy. The compounds change into different ones by exergonic reactions. There are two types of respiration: Made-to-order essay as fast as you need it Each essay is customized to cater to your unique preferences +...
Mitosis and meiosis are two different forms of reproduction in eukaryotic cells. These two processes are similar in some aspects while different in others. Both result in the creation of new cells, but through different methods. Mitosis is a type of asexual reproduction, while meiosis...

There was a time when man used to pass things we couldn’t see. Lots of things are invisible, but that does not suggest they’re not there. Yet Scientists knew it from centuries that the insides of all living beings are made up of tiny cells....
Polymers are large molecules and have the same structural unit repeating over and over and these repeating units are known as monomers. These monomers are attached with each other with covalent bonds and form polymers. Polymers generally consist of high molecular weight and over 10000...
Introduction Animal cells, the fundamental building blocks of life, harbor a remarkable complexity of structures and functions. This essay delves into the intricacies of animal cell machinery, exploring the vital components that enable life’s processes to occur. We will uncover the architecture of these cells...
Microbial Growth In this lab we measured the absorbance, at 15 minute intervals, of Escherichia coli in tryptic soy broth using a spectrophotometer. Using measurements of optical density (OD) provided by the spectrophotometer we are then able to calculate the values for growth rate (k)...
