The correct answer is option B, that is, photosynthesis.  

The procedure by which some kinds of bacteria, plants, and certain protozoans utilize the energy from the sunlight to generate glucose from water and carbon dioxide is known as photosynthesis. It does not take place in animals.  

This glucose produced is then transformed into pyruvate that discharges ATP by the process of cellular respiration, in the process oxygen is also produced.

During photosynthesis, the energy used to pump protons comes from ___________, whereas in cellular respiration it comes from ___
Annette [7]

During photosynthesis, the energy used to pump protons comes from ______light_____, whereas in cellular respiration it comes from ______NADH/FADH₂_______.

<h3>What are the steps in photosynthesis?</h3>
  1. The first step in photosynthesis is the absorption of light by chlorophyll bound to chloroplast thylakoid proteins. The absorbed light energy is used to remove electrons from electron donors such as water to form oxygen.
  2. The electrons are then transferred to the primary electron acceptor, quinine (Q.). Electrons are further transferred from the primary electron acceptor to the final electron acceptor (usually NADP⁺).
  3. Proton transfer from the thylakoid lumen to the stroma via the F₀F₁ complex generates ATP from ADP and Pi.
  4. The NADP and ATP produced in steps 2 and 3 provide the energy, and the electrons power the process of reducing the carbon to a six-carbon sugar molecule.

The first three steps of photosynthesis, are directly dependent on light energy and are thus, called light reactions, while the reactions in the last step are independent of light and thus are termed dark reactions.

Why are proteins considered organic molecules?
snow_lady [41]

Answer:

A) They contain many carbon atoms.

Explanation:

Proteins are considered organic molecules because they are made up of carbon atoms. Proteins give your body energy and allows your body to run the way it does. Proteins also aren't considered organic molecules because they are small, because they are not used by living things, or because they contain nitrogen.

Hope this helps.
