The bonding of an enzyme to its substrate forms an enzyme-substrate complex. The catalytic action of the enzyme converts its substrate into the product or products of the reaction. Each reaction is extremely specific‚ distinguishing between closely related compounds‚ including isomers. For example‚ the enzyme sucrase will only act on sucrose and will not bind to any other disaccharide. The molecular recognition of enzymes is due to the fact that they are proteins‚ which are defined as being macromolecules

Probability (or likelihood[1]) is a measure or estimation of how likely it is that something will happen or that a statement is true. Probabilities are given a value between 0 (0% chance or will not happen) and 1 (100% chance or will happen).[2] The higher the degree of probability‚ the more likely the event is to happen‚ or‚ in a longer series of samples‚ the greater the number of times such event is expected to happen. These concepts have been given an axiomatic mathematical derivation in probability theory

events occurred during the six week period. The event at Nanjing is called many names such as rape‚ massacre‚ battle‚ or invasion. It is still debated on the appropriate term to be used to describe the event at Nanjing. A massacre would be the most appropriate term for the next textbook for ninth graders to describe the event at Nanjing because the Japanese army murdered about 300‚000 Chinese people whereas the amount of Japanese killed could not even compare. The event at Nanjing would be described

Pg. 287 #1‚3‚4 1. Describe the structure of a nucleotide. A nucleotide is a sugar molecule that has 3 parts including a simple sugar‚ a phosphate group and a nitrogenous base. Nucleotides join together forming long chains‚ with the phosphate group of nucleotide bonding to the deoxyribose sugar of an adjacent nucleotide. 3. Explain why the structure of a DNA molecule is often described as a zipper. The structure of a DNA molecule is often described as a zipper because it is made of tow chains

chemically sterile‚ insect-free world." DDT was sprayed over any and all crops that mosquitoes could be found on‚ which started leaking the harmful chemicals into the food supply. However‚ since testing was only done to determine the short-term effects of DDT‚ no one knew how dangerous the chemicals could be. The dangers of a bug-free world were also largely unknown as well‚ until Rachel Carson wrote Silent Spring in 1962. Silent Spring told a

QUESTION 1 Describe in detail‚ the simple changes in synapses that happen during classical conditioning. Discuss the extent to which all forms of learning can be explained by these simple synaptic synaptic changes. The brain’s ability to learn‚ to change in response to experience and to store/retrieve learning through memory it is a fascinating process fundamental to one’s existence. The first scientific study of animal learning demonstrated a form of associative learning - classical
