Answer:

The correct answer is C) mitochondrial inner membrane

Explanation:

The proteins involved in the electron transport chain is located in the inner mitochondrial membrane. There are four protein complexes present in the inner mitochondrial membrane which makes the electron transport chain.

NADH dehydrogenase, succinate coenzyme Q reductase, coenzyme Q- cytochrome c reductase, cytochrome c oxidase are the 4 enzyme complex that are present in the inner mitochondrial membrane and makes electron transport chain.

NADH is the reduced molecule which feeds electron in the ETC and the final electron acceptor is oxygen. So the right answer is C.

Answer:

Mitochondrial inner membrane. (Ans. C)

Explanation:

Proteins of the electron transport chain present in the mitochondrial inner membrane. The electron transport chain at the inner mitochondrial membrane forms a proton gradient, which is driving the synthesis of ATP with the help of chemiosmosis.

Oxygen forms water by accepting electrons, and picking up protons, and it sits at the end of the ETC. In the absence of oxygen ETC will stop running, and chemiosmosis will no longer able to produce ATP. Cells are not able to carry out the reaction they need to function, and may die after a long period, in the absence of ATP.

That would be myology. Myology is the study of the muscular system, wlong with its nature, structure, functions and diseases. It mainly deals with the three types of muscles found in the human body: skeletal muscles, smooth muscles, and cardiac muscles. Muscles are also categorized depending on whether or not they are voluntary or involuntary. Myology is concerned with the study of all this and much more.

Xavier drew a diagram to compare the roles of oxygen and hydrogen in photosynthesis.

Elan Coil [88]

Answer:

Is released into the air through stomata

Explanation:

Oxygen and hydrogen both exists as gaseous molecules in the atmosphere. However, one of them (oxygen) is a product of photosynthesis while the other (hydrogen) is one of the constituents of the molecule that starts the process of photosynthesis.

According to this question, the X used in the attached diagram is the role of oxygen in photosynthesis. Oxygen is released as a product of photosynthesis and goes out of the plant into the air via the STOMATA. Hence, the gas released into the air via stomata is OXYGEN.

Which of the following is true of the bones of the forearm?

Elza [17]

Answer: b. The radius forms the point of the elbow

c. The radius articulates to the wrist closest to the thumb

Explanation:

Ulna and radius are the two bones of the forearm. These bones articulates with the humerus and carpels of the hand.

b. The radius forms the point of the elbow: The elbow joint is the hinge joint that forms between the proximal ends of the radius and ulna in the forearm and distal ends of the humerus. The radius forms a pointed end.

c. The radius articulates to the wrist closest to the thumb: The wrist forms a complex joint. It forms a transition between the hand and the forearm. The radial deviation in the wrist forms the basis for the movement of the tilting of the wrist joint towards the thumb.
