B. Muscle cell, also known as myocytes, have more abundant mitochondria than the other cells listed. This is primarily due to the fact that sustained muscular contractions require massive amounts of cellular energy, transported throughout the cell within the phosphate bonds of Adenosine Tri-Phosphate (ATP) molecules. Mitochondria are the cells' organelles that produce ATP, giving them the nickname "energy powerhouses of the cell."
Answer:
The answer is silicon, oxygen, and one or more metal elements
Explanation:
Answer:
a. the pH within the thylakoid is less than that of the stroma
Explanation:
The pH of thylakoid membrane is 8 at normal conditions but it became highly acidic like 4 during photosynthesis. The electron transport chain utilize the energy released by excited electrons to pump the H+ ions to lumen of thylakoid membrane from stroma during light reaction of photosynthesis. The H+ ions are present in both the stroma and thylakoid membranes. These high potential H+ ions are utilized by ATP synthase complex for the production of ATP.
We know that more the H+ ions lesser will be the pH and lumen have the high concentration of H+ ions. While the pH of stroma is normally kept acidic by plants to create a concentration and potential difference of H+ ions for the production of ATP. That why the lumen have lower pH than stroma of chloroplast.
Answer:
Cellular respiration takes place in mitochondria of a cell, hence it is also known as power house of cell , because it gives us energy in the form of ATP molecule .
