nucleic acids. Each classification performs specific functions that allow cells to grow and survive. Macromolecules can be either split or bonded through dehydration synthesis or hydrolysis. Dehydration synthesis occurs when water is released‚ electrons become shared‚ covalently bonding two monomers together. Hydrolysis takes place when water is added to a polymer‚ energy is released and the covalent bonds break‚ turning the polymer into monomers. The ratio of carbon to hydrogen to oxygen is 1:2:1

Zellweger syndrome is one of a group of four related diseases called peroxisome biogenesis disorders‚ a group of deadly genetic diseases that claim the lives of children usually before they reach their first birthday. This syndrome is the most common type of peroxisome biogenesis disorder. The disease is caused by defects in any one of 13 genes‚ called PEX genes‚ required for the normal formation and function of peroxisomes. Peroxisomes are cell structures that break down toxic substances and synthesize

Introduction Weathering is the breakdown and alteration of rocks and minerals at or near the Earth’s surface into products that are more in equilibrium with the conditions found in this environment. Most rocks and minerals are formed deep within the Earth’s crust where temperatures and pressures differ greatly from the surface. Because the physical and chemical nature of materials formed in the Earth’s interior are characteristically in disequilibrium with conditions occurring on the surface.

Weathering- is a process where rocks are physically broken down or chemically modified by climatic or biological elements. Works through 3 processes: physical weathering‚ chemical weathering and biological weathering. Physical weathering- is the breaking down of rocks into smaller fragments brought about by physical (mechanical) forces. Works through 4 processes: alternate expansion and contraction‚ frost action‚ pressure release and salt crystal growth. Alternate expansion and contraction- this

involved the hydrolysis of milk protein concentrates which uses using chymotrypsin‚ pepsin and trypsin to improve the solubility and functionality of milk protein concentrates. With the pH levels adjusted the powdered milk was hydrated and then it was mixed with the aforementioned enzymes during the experiment. To provide 1g of enzyme for every 100 g of protein the enzyme solutions were added that was being hydrolyzed. The results of the study was that the milk protein concentrate hydrolysis with chymotrypsin

Bio Cement The project aims at attaining high durability of concrete and gaining high strength of cement. We plan to make use of bacterial species which can hydrolyze the enzyme Urease efficiently to produce microbial concrete. Such bacterial are known to produce calcium which is useful in giving strength to cement. We are working in 2 stages. Stage 1: Here we check the effect of bacterial solution on cement mortar and along with that we check the effectiveness of the bacterial solution

Review Sheet Exercise 8 Chemical and Physical Processes of Digestion NAME Dane Wilson LAB DATE/TIME august 4th Carbohydrate Digestion The following questions refer to Activity 1: Assessing Starch Digestion by Salivary Amylase. 1. At what pH did you see the highest activity of salivary amylase? Why? 7.0 because that is when the salivary is most effective and it breaks down carbohydrates. 2. How do you know that the amylase did not have any contaminating maltose

a body undergoes after death. It is the decay of tissues and structures. There are two types of decomposition: abiotic and biotic. Abiotic decomposition is defined as the degradation of a substance by chemical or physical processes; such as hydrolysis‚ reduction‚ or oxidation. Biotic decomposition is the metabolic breakdown of materials into simpler components by living organisms. This is typically done by microorganisms. “The [decomposition] process is essential for recycling the finite
