Hi! I was about to answer your question.

If the hydrogen pump protein in photosystem II does not have enough H+ ions into the thylakoid there will be a decrease in the production of ATP and a decrease in the production of NADPH.

The right answer is there will be a decrease in the production of ATP and NADPH.

ATP synthase chloroplasts (such as mitochondria and bacteria) is an ATPase type F, also called F1Fo ATPsynthase. When the proton gradient is favorable, the enzyme couples the synthesis of ATP (from ADP and Pi) to the spontaneous proton flux that takes place towards the membrane face (outwards). . It should be noted that if there is no proton gradient (neither membrane potential nor pH gradient) to direct the synthesis reaction, or the hydrogen can not pass through the enzyme, the Equilibrium constant of the reaction favors the reverse reaction of hydrolysis (ATPase activity) and therefore no formation of ATP and moreover no formation of NADPH from H +.

Answer: True

Explanation:

The dual energy x-ray absorptimetry is a technique that is used for measuring the bone mineral density. This technique utilizes the two X-ray beams with different levels of energy. The soft tissues are subtracted in this procedure and the beam is absorbed by the bone. This technique is useful for diagnosis of osteoporosis, to check and diagnose the infected, fractured and healing bones.

Fluid retention is a condition in which excess fluid due to capillary leakage or any other reason fills up inside the circulatory system, body tissues and cavities. The following symptoms will appear:

Discolored skin, aches and tenderness in the limbs, stiffness in joints and weight gain.

The retained excess fluid may react with the X-ray beam hence, will interfere in the process of diagnosis. Thus caution should be taken for such individuals.

kap26 [50]

The answer is an increase in ketones. High ketones in the blood from diabetes type I causes diabetic ketoacidosis. Due to the insensitivity of cells to insulin (or lack of production of insulin in the body by the pancreas), the cells are unable to take in glucose for metabolisms, hence the body breaks down fatty acids and amino acids for energy. The metabolites of fatty acid metabolism and the deamination of amino acids are ketones (keto acids) that decrease the blood’s pH.
