Answer:
The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.

The statement that when consumed together, grains and legumes are good complementing protein sources is true.<span>
</span><span>Legumes are plants that include beans, lentils, peas and peanuts, while grains are </span><span>wheat, oats, corn, rice..</span><span>
They are less expensive than meat, poultry and fish.
</span>When eaten together provide a complete protein essential for health.
1) Both involve electron transport chains.
<span>2) Chemiomosis allows ATP synthase to produce ATP. </span>
<span>3) Both take place at some point within an organelle (mit. = CR, chloroplast= photo.) </span>
<span>4) Both utilize ATP for energy at some points. </span>
<span>5) Both provide power for cellular activities. </span>
<span>5 Differences </span>
<span>1)Cellular respiration depends on oxygen as a substrate. </span>
<span>2)Photosythesis utilizes 2 electron transport chains (not just 1). </span>
<span>3)In Photo. , energy is provided by photons and not catabolic processes as in cell. resp. </span>
<span>4)Photosynthesis involves the production of NADPH (CR involves NADH and FADH2) </span>
<span>5)Photosynthesis involves CO2 and H20 as substrates (splitting h20 provides the electrons for the process).</span>
