Answer:
B
Explanation:
This H+ ion gradient is referred to as a proton motive force. It is created using energy from the Krebs cycle in the matrix of the mitochondria. As electrons are passed from one protein complex to another, reducing molecules such as NADH and FADH2, the protons are pumped to the intermembrane space of the mitochondria. ATP synthase uses this potential to generate ATP as the H+ ions move downgradient (back to the matrix) through channels in the protein enzyme.
Answer:
Buffy coat.
Explanation:
Between the plasma, and red blood cells the platelets, and white blood cells form a thin white layer which is known as Buffy coat following density gradient centrifugation of the blood.
Centrifugation is the process where the distinguish between cell fragments, and cell from the liquid intracellular matrix occurs. Centrifugation is a technique which separates the particles according to their size, density, viscosity and shape with the help of centrifugal force.
Answer:
Hypotonic
Explanation:
At this point, the cell is turgid (very firm), the healthy state for most plant cells. Plants that are not woody, such as most houseplants, depend for mechanical support on cells kept turgid by a surrounding hypotonic solution
