The first turbo-diesel production car was the Mercedes-Benz 300SD (W116) saloon, which was sold in the United States from mid-1978 and powered by the OM617 five-cylinder engine. [25] A year later, the Peugeot 604 D Turbo became the first turbo-diesel car to be sold in Europe. Turbo-diesel cars began to be widely built and sold in Europe during ...
A turbocharger does not place a direct mechanical load on the engine, although turbochargers place exhaust back pressure on engines, increasing pumping losses. [ 53 ] Supercharged engines are common in applications where throttle response is a key concern, and supercharged engines are less likely to heat soak the intake air.
In cell respiration, the proton pump uses energy to transport protons from the matrix of the mitochondrion to the inter-membrane space. [1] It is an active pump that generates a proton concentration gradient across the inner mitochondrial membrane because there are more protons outside the matrix than inside.
An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [1]It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three-dimensional exploded diagram.
There are several modes by which membrane channels operate. The most common is the gated channel which requires a trigger, such as a change in membrane potential in voltage-gated channels, to unlock or lock the pore opening. Voltage-gated channels are critical to the production of an action potential in neurons resulting in a nerve impulse.
Other cellular extensions that protrude from the cell membrane are known as membrane protrusions or cell protrusions, also cell appendages, such as flagella, and microvilli. [ 8 ] [ 9 ] Microtentacles are cell protrusions attached to free-floating cells, associated with the spread of some cancer cells .

In terms of membrane transport the gradient is of interest as it contributes to decreased system entropy in the co-transport of substances against their gradient. One of the most important pumps in animal cells is the sodium potassium pump, that operates through the following mechanism: [9]
