Answer:

The correct answer is option D.

Explanation:

Photosystem II is a special pigment-protein complex that utilizes a photon to excite the electron and transfer of electrons from water to PQ or plastoquinone. That resulting in the generation of oxygen and the release of reduced PQ into the photosynthetic membrane.

Steps involved in photosystem:

When a photon hit photosystem II, light energy absorbed by one of the pigments in photosystem II, energy is carried from one pigment to another and reach down to the reaction center .

ATP synthesis

Light absorption in PSI

NADPH formation.

Thus, The correct answer is option D.

The answer is most likely to be D, because when the photon hits an electron within a molecule of chlorophyl, the energy from the light excites an electron from its normal energy level to an excited energy level!

which statement correctly compares and contrast the three stages of cellluar respiration that occurs in the presence of oxygen
Lapatulllka [165]
<h2><u>Full Question:</u></h2>

Which statement correctly compares and contrasts the three stages of cellular respiration that occur in the presence of oxygen? Each stage occurs in the mitochondria, but only the final stage produces ATP. Each stage produces ATP, but only the third stage occurs in the mitochondria. Each stage produces ATP, but only the first stage occurs in the cytoplasm. Each stage occurs in the cytoplasm, but only the final stage produces ATP.

<h2><u>Answer</u>:</h2>

Each stage produces ATP, but only the first stage occurs in the cytoplasm.

<h3><u>Explanation</u>:</h3>

Cellular respiration is the process by which the glucose or any respiratory substrate is burned down inside a cell producing ATP or energy. This process of cellular respiration is seen in each and every living cell. The glucose is burned in the cytoplasm of the cell producing the pyruvate. This pyruvate is decarboxylated into Acetyl CoA and transferred inside the mitochondria. So the glycolysis or the 1st step of cellular respiration occurs in cytoplasm and rest inside the mitochondria.

ATP is produced from each astep of cellular respiration. So the correct option is option C.

What equipment should a food worker use to reheat a baked potato?
sp2606 [1]

If you want to reheat potatoes that are already cooked on a pan or fried, they may mash or dry, especially if they are fried. Better to avoid this practice for taste reasons, even if we can possibly heat them in the pan.


How to do?

To reheat potatoes boiled in water or steam, fry them in the pan: this is the best way to get the right result to taste, and you can also heat them in the microwave. cutting them into pieces so that reheating is easier and more uniform.

Which two phrases describe a situation that will cause a stationary object to start moving?
Varvara68 [4.7K]

Answer:

A .a net force greater than zero

B. Unbalanced Force

Explanation:

A .When the resultant force on an object is zero, it will remain at rest if it is at rest, or continue to move in a straight line at a constant velocity if it is in motion. So , the answer will be a net force greater than zero .

B . An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion. A net force = unbalanced force. So , the answer will be unbalanced forces .
