Cellular respiration is a process of breaking down sugar into carbon dioxide and water. Cellular respiration releases energy that cells use to do what they do. ... Breathing bring oxygen to cells and carries carbon dioxide away from cells. Cellular respiration breaks down sugar to release energy.
Answer:
A. More hydrogen ions inside the membrane than outside it
Explanation:
During electron transfer from water molecule to PS II and then through electron transport chain to the PS I pumps the hydrogen ions inside the thylakoid lumen. ATP synthesis is driven by energy of proton concentration gradient that moves the hydrogen ions (protons) from lumen of thylakoid membrane towards the stroma. Hence, ATP synthesis requires presence of more hydrogen ions inside the membrane.
Answer: The hair root is deep in the dermis at the hair bulb, and includes a layer of mitotically active basal cells called the hair matrix. The hair bulb surrounds the hair papilla, which is made of connective tissue and contains blood capillaries and nerve endings from the dermis
