<span>The trick here is to understand the definition of each of the cellular transport or function mechanisms listed. These are some interesting (and strange) analogies!

Facilitated Diffusion
This is when a mechanism assists in diffusing (spreading) some material into an environment. The dog on the wagon going through a spring loaded door would shoot it out into the environment. This is an odd analogy but Point 3 would be the one.

Active Transport 
Is when energy is expended to transport molecules somewhere against a concentration gradient or some other barrier. Examples include transporting molecules across a cell wall. The best analogy is the dog being dragged into a bathtub (Point 1).

Phagocytosis 
This is when a larger cell consumes a molecule often like eating. This matches to point 2 - the child eating the doughnut.

Passive Diffusion
Is when a concentration of molecules naturally diffuse into an environment. This suits point 5 - the crowded room full of people.

Pinocytosis
Is the budding of cell membranes to consume liquid in the surrounding environment. I guess a woman drinking tea is the closest analogy listed (Point 4).</span>

Which of the following factors is needed during light-dependent reactions to create ATP and NADPH energy molecules?
Alexeev081 [22]

Answer: The correct answer is- Solar energy, carbon dioxide, and water.

Light dependent reactions comprise the first phase of photosynthesis (formation of food by green plants and algae in presence of sunlight) process.

This phase occurs in the thylakoid membrane of chloroplast.

During this phase, a green pigment chlorophyll absorbs energy from sunlight (in the presence of carbon dioxide and water) and convert it into chemical energy in the form of ATP and NADPH.

This energy is further utilized in the formation of food (glucose) in the next phase, which is a light independent phase of photosynthesis.

In photosynthesis, oxygen is produced by splitting of water molecule and it is released in the atmosphere.

Thus, solar energy, carbon dioxide, and water is the right answer.
