Carbohydrates come in a variety of sizes. Describe the basic chemical structure of carbohydrates and explain how larger ones are made. How do the category names of different carbohydrates relate to the complexity? Finally‚ what are they used for in organisms?

PROTEIN TRANSLATION 1. Initiation Translation To begin translation: large and small ribosomal subunit‚ along with the initiating tRNA‚ assembles onto the mRNA 2. Translation Elongation The next amino acyl-tRNA enters the ribosome at the A site The amino acid at the P site is transferred to the tRNA at the A site. The ribosome moves one codon farther along the mRNA‚ releasing the empty tRNA through the E (exit) site. The A site is free for the next incoming RNA. The cycle is repeated as the

in a certain process that is crucial to existence: the formation of proteins. Although all species differ from each other in various ways‚ the processes by which proteins are synthesized are the same in all. Protein synthesis is a very complex process. In order to understand the process‚ there some basics that are essential for cells to create the proper proteins. DNA is a very long and double-stranded molecule that contains coding‚ through four nitrogen bases (adenine‚ guanine‚ thymine‚ and cytosine)

Explain in detail why palisade cells in plants contain many chloroplasts Palisade cells are cells which are found within the leaves of many plants. They contain chloroplasts‚ which convert the energy in light to chemical energy through photosynthesis. The cylindrical shape of palisade cells allows a large amount of light to be absorbed by the chloroplasts. Beneath the palisade mesophyll are the spongy mesophyll cells‚ irregularly-shaped cells that having many intercellular spaces to allow the passage

Edward F. Coyle’s article‚ Fat Metabolism During Exercise: New Concept‚ focuses on answering the question to “what limits the rate at which people can convert their body fat into energy during exercise. He focuses on the different components of fats‚ such as the adipose tissue‚ blood plasma‚ and the oxidization of fats. He highlights how within the adipose tissue there an estimated 50‚000 to 60‚000 kcal energy stored as triglyceride and an obese individual will have more energy than compared to an

occurs both in fresh and marine waters‚ where excessive development of certain types of algae disturbs the aquatic ecosystems and becomes a threat for animal and human health. The primary cause of eutrophication is an excessive concentration of plant nutrients originating from agriculture or sewage treatment. The purpose of this booklet is to describe in a simple way the causes of eutrophication‚ the environmental effects‚ the associated nuisances and health risk as well as the preventive and mitigating

Paleo diet‚ a lot of people have started deamonizing beans along with grains and dairy. There really isn’t anything wrong with eating beans. The food shaming has got to stop. Beans contain some great nutrients such as fiber‚ and can definitely be part of a healthy diet. They do have some anti-nutrients that can make them hard to digest. Let’s take a look at two of those in more depth. Lectins Lectins are "sticky" proteins that bind to stuff once they are in our systems. Most foods contain them‚
