The Five Major Compounds That Make Up the Human Body The human body is one of the most complex and fascinating things on this planet. There are five major groups of compounds that compose the human body. These are carbohydrates‚ lipids‚ proteins‚ nucleotides‚ and water. These compounds are all very important to humans and without them humans would not be able to survive. Compounds have many functions that encourage a human cell and a human body to function. Compounds are pure substances

just been sequenced. I loaded the draft version of the genbank file into my software pipeline I spent the last two years developing. Minutes later‚ a genome-scale reconstruction of the P. marinus metabolism appeared on my screen. In that moment‚ I knew I was the first person to view the entire metabolism of this cyanobacteria. I remember the chills going down my spine‚ the palpitation of my heart‚ and the rush that comes only from breathing the rarified air of discovery.The original motivation for

There is no precise definition of what separates the living from the non-living. One definition might be the point at which an entity becomes self-aware. In this sense‚ someone who has had severe head trauma may be classified as brain dead. In this case‚ the body and brain are still functioning on a base level and there is definitely metabolic activity in all of the cells that make up the larger organism‚ but it is presumed that there is no self-awareness so the person is classified as brain dead

pattern) Stage Description Diagram Attachment Virus binds to a specific receptor on the host cell surface. Penetration Viral nucleic acid enters the cell. Synthesis of new components. Viral nucleic acid takes over control of the cell metabolism stopping cell’s normal nucleic acid and protein synthesis. Viral nucleic acid is replicated using nucleotides from the host cell. Protein coats are manufactured using the amino acids of the host cell. Assembly Whole virus particles are made

Science 1. A‚ because organisms need carbohydrate‚ vitamins‚ and minerals and other nutrients to gain energy and proteins to live and to continue metabolism. B‚ The amount of energy stored in macromolecules varies because their chemicals structures‚ and there for the energy contain in their chemical differ. 2. 6O2 + 62H1206 -> 6O2 + 6H2O + Energy B The process of cellular respiration provides the energy a cell needs to carry processes‚ which in turn control the cell’s internal conditions.

As we can see on the graph we can tell how clearly glucose has highest respiration rate of 455 ppm/min. Sucrose is second with 391 ppm/min‚ then fructose with 231 ppm/min and lastly lactose with 92 ppm/min. We can see a clear trend‚ that glucose had the highest rates and that lactose was the lowest‚ so we see a clear downwards sloping trend‚ which was also expected. This suggests that yeast respires best with glucose instead of sucrose fructose or lactose. To explain this process‚ we must first understand

stressors. The physiological response process begins when the hypothalamus triggers a factor that inhibits the pituitary gland to secrete ACTH. The adrenal cortex is then aroused by ACTH to secrete cortisol‚ which increases blood sugar levels and metabolism. When metabolic activity is increased in the hippocampus‚ neurons become more sensitive to toxins or over-stimulation. This is a slow process‚ but in the end it helps the body defend itself in the presence of stress. Once the nervous system is
