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>
- 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.
- 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⁺).
- Proton transfer from the thylakoid lumen to the stroma via the F₀F₁ complex generates ATP from ADP and Pi.
- 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.

Answer:
Bactrian camels have two humps rather than the single hump
Explanation:
Answer:
4.
Explanation:
Synteny oe syntenic gene is defined as the physical co-localization of genetic loci on the same chromosome within a speciesand inidvidual.
In the beginning of the meiosis process, when genes are present in the same chromosomes but very far, they undergo indepedent assort due to homologous recombination and the random exchnage of matching fragment in homologous chromosomes takes place. During the crossing over there are very less chances that all types of gametes are produced accurate frequency.
Hence, the correct answer is 4.
A. Citric acid cycle (Krebs cycle)
Explanation:
Primary succession occurs when a habitat that has completely destroyed reheals from complete scratch
On the other hand, secondary succession occurs when only a portion of the original ecosystem survives and is rebuilt from that
