intermembrane space creating a proton gradient. The electrons are then accepted by O2 to make H20. The protons move down their concentration gradient and are pumped back into the matrix by passing though a transport protein called ATP synthase during chemiosmosis. The protons power ATP synthase as they diffuse down the gradient thus catalyzing the production of

primary electron acceptor (PEA). They are then passed onto a series of molecules known as the electron transport chain (ETC). The electrons eventually combine with a proton and NADP+ to form NADPH. Another process called chemiosmosis also occurs in the light reaction. Chemiosmosis is a process in which ATP (energy) is produced. So‚ light‚ H2O‚ ADP and NADP+ are required for the light reaction and O2‚ ATP & NADPH is produced. The ATP and NADPH molecules then go into the dark reactions. In the dark

TOPIC 3.7 + 8.1: CELL RESPIRATION 3.7.1 Define cell respiration. Cell respiration is the controlled release of energy from organic compounds in cells to form ATP (adenosine triphosphates). 3.7.2 State that‚ in cell respiration‚ glucose in the cytoplasm is broken down by glycolysis into pyruvate‚ with a small yield of ATP. Glycolysis in cytoplasm: Glucose 2 pyruvates + small amount of ATP (does not use oxygen) 3.7.3 Explain that‚ during anaerobic cell respiration‚ pyruvate can be

across the membrane—this creates a concentration gradient‚ while O2 is reduced to H2O. In the ATP synthase‚ hydrogen ions diffuse across the semipermeable membrane and convert the potential energy of the proton gradient into chemical energy in ATP (chemiosmosis). Cellular respiration makes a total of 32

require energy are put into a category called active transport‚ while the ways that don’t require energy are put into a category called passive transport. An example of active transport is the proton pump. The proton pump is an integral part of chemiosmosis‚ and it pumps protons from an area of low concentration to an area of high concentration. This requires energy since things like to move from an area of high concentration to an area of low concentration. An example of passive transport is facilitated

thereby reducing it to water. Meanwhile‚ hydrogen ions from the electron transport chain are pumped into the inter-membrane space from the mitochondrial matrix‚ creating a proton gradient that is capable of performing work. In a process called chemiosmosis‚ the synthesis of ATP is coupled with the diffusion of hydrogen ions back into the mitochondrial matrix through ATP

Organisms that synthesize their own nutrients; include some bacteria that are able to synthesize organic molecules from simpler inorganic compounds. cells - The smallest structural units of living matter capable of functioning independently. Chemiosmosis- The process by which ATP is produced in the inner membrane of a mitochondrion. The electron transport system transfers protons from the inner compartment to the outer; as the protons flow back to the inner compartment‚ the energy of their movement
