Biology

prisoha [69]3 years ago

Answer:

Concentration gradient means difference in solute concentration among two regions of a solution.

Explanation:

When there is a difference in solute concentration in the two regions of a solution then the term concentration gradient is used .

      Various membrane transport process such as passive transport(diffusion and osmosis),facilitate transport depends on concentration gradient of solute molecule in both sides of plasma membrane.

      During passive and facilitate diffusion solute molecules are transported along their concentration gradient that means from high concentration region to the region of low concentration until equilibrium is being established.

Which of the following options lists the stages in cellular respiration in the correct order? glycolysis, the citric acid cycle,
marishachu [46]

Answer:

The correct answer is  glycolysis, the citric acid cycle, and oxidative phosphorylation

Explanation:

Aerobic respiration contains three major processes that are glycolysis, the citric acid cycle, and oxidative phosphorylation.  

In glycolysis, partial oxidation of one mole of glucose gives two moles of pyruvate and 2 NADH and 2 ATP. Then this pyruvate is converted into acetyl-CoA in the mitochondrial matrix(in eukaryotes) and acts as a fuel for the Krebs cycle.

In the Krebs cycle, acetyl CoA gives rise to 4 CO₂, 2 ATP, 6 NADH, and 2 FADH₂. So from glycolysis and Krebs cycle, only 4 ATP is produced and most of the energy remains in the form of NADH and FADH₂.

So in oxidative phosphorylation electrons are released from these molecules into machinery of oxidative phosphorylation to synthesize ATP.

How may the height of a water table create a spring
yaroslaw [1]
When prolonged and excessive rainfall the more water percolates and the water table (below the earth surface/soil) rises.  The higher the water table the more the possibility increases for a spring to form in the sense that it would now be easier for the water to find a means of escaping the underground through perhaps a crack or a cave, etc.
