How would anaerobic conditions (when no o2 is present) affect the rate of electron transport and atp production during oxidative phosphorylation? (note that you should not consider the effect on atp synthesis in glycolysis or the citric acid cycle.) a) electron transport would be unaffected but atp synthesis would stop. b) electron transport would stop but atp synthesis would be unaffected. c) both electron transport and atp synthesis would stop. d) neither electron transport nor atp synthesis would be affected

c) Both electron transport and ATP synthesis would stop.

Explanation:

We need oxygen to survive. Absence of oxygen can lead to one's death. This is because we need oxygen so that our cells can use it during oxidative phosphorylation, the last stage of cellular respiration. Oxygen is found at the end of the electron transport chain, where it accepts electrons and picks up protons to form water. Absence of oxygen at this stage will make the electron transport chain to stop running, and ATP will not be produced.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
