AP Biology RespirationCompare and contrast anabolism and catabolism. Give an example of a metabolic pathway that represents each compare and contrast anabolic and catabolic pathways quizlet. Anavar 10mg benefits and catabolism are similar in they are both metabolic pathways Anabolic reactions consume more energy than they produce, and example of an anabolic pathway pathwqys the synthesis of glycogen polysaccharide biosynthesis catabolic reactions produce more energy than they consume an example of a catabolic pathway is respiration. What is the role of enzymes in a biochemical pathway? Describe the details of the process of how an enzyme pathwas up a chemical reaction, including the structure of the enzyme. The surface of the substrate contacts a specific region of the surface of the enzyme molecule called the active site 2.

Explain the role of catabolic and anabolic pathways in cellular respiration. Catabolic pathways release the energy stored in complex molecules through the breakdown of these molecules into simpler compounds. Anabolic pathways, sometimes called biosynthetic pathways, require energy to combine simpler molecules into more complicated ones. Distinguish between exergonic and endergonic reactions i terms of free energy change.
Exergonic reaction proceeds with a net release of free energy and is spontaneous. Endergonic reactions are nonspontaneous; they must absorb free energy from the surroundings. Describe the function of enzymes in biological systems.
Are biological catalysts agents that speed the rate of a reaction but are unchanged by the reaction. Explain why an investment of activation energy is necessary to initiate a spontaneous exergonic reaction.
Investment of activation energy is known as a free energy of activation where the energy that must be absorbed by reactants to reach the unstable transition state, in which bonds are likely to break, and form which the reaction can proceed.
Understand the elements of a reaction diagram. Explain how feedback inhibition prevents a cell from wasting chemical resources. The product of a pathway acts as an allosteric inhibitor of an enzyme early in the pathway. A free energy of activation where the energy that must be absorbed by reactants to reach the unstable transition state, in which bonds are likely to break, and form which the reaction can proceed.
A pocket groove on the surface of the protein where catalysis occurs. Consists of nitrogenous base adenine bonded to the sugar ribose, which is connected to a chain of three phosphate groups. Require energy to combine simpler molecules into more complicated ones. Release the energy stored in complex molecules through the breakdown of these molecules into simpler compounds. A chemical agent that increases the rate of a reaction without being consumed by the reaction.
A form of potential energy that is available for release in chemical reactions. Are nonspontaneous; they must absorb free energy from the surroundings. The substrate is temporarily bound to its enzyme. Proceeds with a net release of free energy and is spontaneous.
A metabolic pathway is switched off by the inhibitory binding of its end product to an enzyme that acts early in the pathway. The portion of a system's energy available to perform work when the system's temperature and pressure are uniform. Capacity of matter to cause change as a consequence of its location or arrangement.
The reactant on which an enzyme works.
