Energy matters: presynaptic metabolism and the maintenance of synaptic transmission

Synaptic activity imposes large energy demands that are met by local adenosine triphosphate (ATP) synthesis through glycolysis and mitochondrial oxidative phosphorylation. ATP drives action potentials, supports synapse assembly and remodelling, and fuels synaptic vesicle filling and recycling, thus sustaining synaptic transmission. Given their polarized morphological features — including long axons and extensive branching in their terminal regions — neurons face exceptional challenges in maintaining presynaptic energy homeostasis, particularly during intensive synaptic activity. Recent studies have started to uncover the mechanisms and signalling pathways involved in activity-dependent and energy-sensitive regulation of presynaptic energetics, or ‘synaptoenergetics’. These conceptual advances have established the energetic regulation of synaptic efficacy and plasticity as an exciting research field that is relevant to a range of neurological disorders associated with bioenergetic failure and synaptic dysfunction.

Which of the following is not required for the synthesis of ATP by chemiosmosis?

The correct option is A NADPH The synthesis of ATP from ADP during light reaction of photosynthesis is called photophosphorylation. Chemiosmotic hypothesis was proposed by Mitchell to explain the synthesis of ATP. Chemiosmosis involves the movement of ions across a biological membrane along the concentration gradient and it helps in the synthesis of ATP. During the light dependent reactions of photosynthesis, there is an accumulation of protons inside the lumen of thylakoids. The number of protons is high inside the lumen of thylakoids when compared to the stroma of chloroplast. This creates a proton gradient and the breakdown of this gradient generates ATP. The gradient is broken down due to the movement of protons across the membrane into the stroma through ATP synthase. The chloroplast ATP synthase has two parts: C F 0 located in the thylakoid membrane and C F 1 that protrudes on the outer surface of the thylakoid membrane facing the stroma. The C F 0 forms a transmembrane channel for the movement of protons due to which energy is released and that causes conformational changes in the CF 1 of the enzyme. Utilising this energy, ATP is synthesised from ADP by the enzyme ATP synthase. Hence, the synthesis of ATP by chemiosmosis requires a membrane, a proton pump, a proton gradient and ATP synthase. ATP and NADPH are assimilatory powers produced during light reaction of photosynthesis.

These are called electrogenic transporters and electroneutral transporters, respectively. "The membrane-bound copper transporting adenosine triphosphatase (Cu-ATPase), which selectively binds copper ions, transports copper ions into and out of cells (Harris et al. 1998)." Source: Structure [ ] The Mechanism [ ] ATPase (also called F 0F 1-ATP Synthase) is a charge-transferring complex that catalyzes ATP to perform ATP synthesis by moving ions through the membrane. The coupling of ATP hydrolysis and transport is a chemical reaction in which a fixed number of solute molecules are transported for each ATP molecule hydrolyzed; for the Na +/K + exchanger, this is three Na + ions out of the cell and two K+ ions inside per ATP molecule hydrolyzed. Transmembrane ATPases make use of ATP's chemical potential energy by performing mec...

What enzymes make ATP?

ATP synthase: • Enzyme ATP synthase produces ATP by the process of chemiosmosis. • ATP synthase leads to ATP synthesis with proton gradient developed across the inner mitochondrial membrane during cellular respiration as well as across the thylakoid membrane during photosynthesis. • ATP synthase is structurally F-ATPases which is made up of two subunits F0 and F1.

Adenosine Triphosphate Synthesis

Adenosine Triphosphate Synthesis ATP synthesis by FoF1 consists of three step: (1) proton translocation through Fo, (2) conformation transmission to F1, and (3) ATP synthesis in the β unit.

Gautheron, Catherine Godinot, in Living Systems As Energy Converters, 1977 OVERALL ORGANIZATION OP ATP SYNTHASE The mechanism of ATP synthesis still represents a major challenge for biochemists. However, ATP-synthase complexes seem to have many features in common. Their integration in specialized membranes is compulsory for the coupling of ATP synthesis and created the necessary hydrophobic environment, vectorial phenomena and transport problems. More and more information is available about the protein components associated with the ATP-synthase complex and it has become evident that these components are very similar in all transducing membranes. On the basis of experimental data obtained with mitochondrial inner membranes, the whole complex called oligomycin-sensitive ATPase (Pig. 2) consists of three parts: a very hydrophobic membrane sector, a stalk sector, and the F 1 sector which protudes from the inner face of the inner membrane and can be more or less easily dissociated and isolated as a soluble ATPase. This soluble F...
