Question
a. is usually a carbu supplies energy to start a chemical reaciu is specific to one chemical reaction is consumed each time it is used raises the energy barrier for a chemical reaction d. e. 2. Fill in the blanks using the word choices shown below. Some choices may not be used at all. (4 pts) An enzyme is considered a(n) because it speeds up a chemical reaction without being used up. When enzymes are involved in a reaction, a reactant is often called a(n) of its An enzyme is specific because the shape matches only particular reactants. An enzyme speeds up reactions by lowering the The between an active site and its substrate often strains bonds, and helps the reaction proceed. A(n) which is often an inorganic ion, binds to an enzyme and plays a role in catalysis. High temperatures or changes in pH can an enzyme, causing it to lose its shape and biological activity. Chemicals that interfere with an enzyme's ability to function are called Word choices: speeds up, activation energy, product, induced fit, reduced fit, substrat catalyst, active site, active lifestyle, denature, renature, the hature, coenzyme, cofacto 3. Rank the steps for cellular respiration in the correct order (1first). (3 pts) a. Electrons from NADH and FADH2 move through electron transport sys NADH and FADH2 delivered to ETC He flow through ATP synthase (chemiosmosis) H+ gradient generated d. e. -Electrons power the proton pump which pumps H+ Draw a graph of of an exergonic reaction, with progress of reaction on the x-a a. Next, add a dotted line representing the same reaction in the presen f Glucose is oxidized, its hydrogen and electrons are given to NAD+a energy on the y-axis.
