The division of a mitochondrion within a cell to form two or more separate mitochondrial compartments.

The autophagic process in which mitochondria are delivered to the vacuole and degraded in response to changing cellular conditions.

The process of introducing a phosphate group on to a protein.

The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of a ubiquitin group, or multiple ubiquitin groups, to the protein.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, e.g. superoxide anions, hydrogen peroxide (H2O2), and hydroxyl radicals.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a mitochondrion; includes mitochondrial morphogenesis and distribution, and replication of the mitochondrial genome as well as synthesis of new mitochondrial components.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a mitochondrion; includes mitochondrial morphogenesis and distribution, and replication of the mitochondrial genome as well as synthesis of new mitochondrial components.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a mitochondrion; includes mitochondrial morphogenesis and distribution, and replication of the mitochondrial genome as well as synthesis of new mitochondrial components.

The process of synaptic transmission from a neuron to a muscle, across a synapse.

Any process that decreases the frequency, rate or extent of merging of two or more mitochondria within a cell to form a single compartment.

Any process that modulates the frequency, rate or extent of a process involved in the formation, arrangement of constituent parts, or disassembly of a mitochondrion.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of sperm mitochondria; the process in which they take on their characteristic morphology; they are flattened, elongated, and arranged circumferentially into a tight helical coil around the tail-dense fibers of the mature sperm.

Programmed cell death of an errant germ line cell that is outside the normal migratory path or ectopic to the gonad. This is an important mechanism of regulating germ cell survival within the embryo.

Any process that stops, prevents, or reduces the frequency, rate or extent of programmed cell death, cell death resulting from activation of endogenous cellular processes.

Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process in neurons.

The process whose specific outcome is the progression of the compound eye over time, from its formation to the mature structure. The compound eye is an organ of sight that contains multiple repeating units, often arranged hexagonally. Each unit has its own lens and photoreceptor cell(s) and can generate either a single pixelated image or multiple images, per eye.

The directed movement of the mitochondrion to a specific location.

Any process that increases the rate, frequency or extent of mitochondrial fission. Mitochondrial fission is the division of a mitochondrion within a cell to form two or more separate mitochondrial compartments.

Any process that modulates the frequency, rate or extent of mitochondrial electron transport, NADH to ubiquinone.

The memory process that deals with the storage, retrieval and modification of information received a short time (up to about 30 minutes) ago. This type of memory is typically dependent on direct, transient effects of second messenger activation.

The directed movement of a mitochondrion along a microtubule, mediated by motor proteins.

Any process that activates or increases the frequency, rate or extent of establishment of a pattern of pigment in the compound eye.

Any process that establishes the spatial arrangement of mitochondria within the cell.

The memory process that deals with the storage, retrieval and modification of information received at a time ago that is intermediate between that of short and long term memory (30min - 7hrs in Drosophila melanogaster).

Any process that activates or increases the frequency, rate or extent of locomotor rhythm.

Any process that activates or increases the frequency, rate or extent of neuronal action potential.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.

A product of the fusion of the mitochondria during spermatogenesis. After the completion of meiosis the mitochondria of the spermatid collect along side the nucleus and fuse into two masses; these wrap around each other to produce the spherical Nebenkern. During flagellum elongation the Nebenkern unfolds and the two derivatives (major and minor mitochondrial derivatives) elongate down the axoneme.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
