Denaturation of an enzyme occurs when the protein structure is disrupted, eliminating the ability to catalyze reactions. b. Environmental temperatures and pH outside the optimal range for a given enzyme will cause changes to its structure, altering the efficiency with which it catalyzes reactions.

ENE	1.H	Describe the role of energy in living organisms.
	1.H.1	All living systems require constant input of energy.	Cellular Respiration Enzymes & Energy
ENE	1.H.2	Life requires a highly ordered system and does not violate the second law of thermodynamics— a. Energy input must exceed energy loss to maintain order and to power cellular processes. b. Cellular processes that release energy may be coupled with cellular processes that require energy. c. Loss of order or energy flow results in death.
ENE	1.H.3	Energy-related pathways in biological systems are sequential to allow for a more controlled and efficient transfer of energy. A product of a reaction in a metabolic pathway is generally the reactant for the subsequent step in the pathway.
ENE	1.I	Describe the photosynthetic processes that allow organisms to capture and store energy.
ENE	1.I.1	Organisms capture and store energy for use in biological processes— a. Photosynthesis captures energy from the sun and produces sugars. i.Photosynthesis first evolved in prokaryotic organisms ii. Scientific evidence supports the claim that prokaryotic (cyanobacterial) photosynthesis was responsible for the production of an oxygenated atmosphere. iii. Prokaryotic photosynthetic pathways were the foundation of eukaryotic photosynthesis.

ENE	1.J.2	Photosystems I and II are embedded in the internal membranes of chloroplasts and are connected by the transfer of higher energy electrons through an electron transport chain (ETC).
ENE	1.J.3	When electrons are transferred between molecules in a sequence of reactions as they pass through the ETC, an electrochemical gradient of protons (hydrogen ions) is established across the internal membrane.
ENE	1.J.4	The formation of the proton gradient is linked to the synthesis of ATP from ADP and inorganic phosphate via ATP synthase.
ENE	1.J.5	The energy captured in the light reactions and transferred to ATP and NADPH powers the production of carbohydrates from carbon dioxide in the Calvin cycle, which occurs in the stroma of the chloroplast.

ENE	1.K.2	Cellular respiration in eukaryotes involves a series of coordinated enzyme-catalyzed reactions that capture energy from biological macromolecules.
ENE	1.K.3	The electron transport chain transfers energy from electrons in a series of coupled reactions that establish an electrochemical gradient across membranes— a. Electron transport chain reactions occur in chloroplasts, mitochondria, and prokaryotic plasma membranes. b. In cellular respiration, electrons delivered by NADH and FADH are passed to a series of electron acceptor2s as they move toward the terminal electron acceptor, oxygen. In photosynthesis, the terminal electron acceptor is NADP+. Aerobic prokaryotes use oxygen as a terminal electron acceptor, while anaerobic prokaryotes use other molecules. c. The transfer of electrons is accompanied by the formation of a proton gradient across the inner mitochondrial membrane or the internal membrane of chloroplasts, with the membrane(s) separating a region of high proton concentration from a region of low proton concentration. In prokaryotes, the passage of electrons is accompanied by the movement of protons across the plasma membrane. d. The flow of protons back through membrane-bound ATP synthase by chemiosmosis drives the formation of ATP from ADP and in organic phosphate. This is known as oxidative phosphorylation in cellular respiration,and photophosphorylation in photosynthesis. e. In cellular respiration, decoupling oxidative phosphorylation from electron transport generates heat. This heat can be used by endothermic organisms to regulate body temperature.
