Answer: Mitochondria.

Explanation: The electron transport chains is a process that is used for extracting energy by oxidation of NADH and FADH molecules produced during Glycolysis and Kreb's Cycle.

Energy released during ETC is used for the formation of ATP molecules.The ETC takes place in the inner mitochondrial membrane in Eukaryotes.

In Type I diabetes, the body fails to produce insulin and, thus, individuals must inject themselves with insulin before eating.
Annette [7]

Explanation:

<em>Excess insulin in the bloodstream causes cells in your body to absorb too much glucose (sugar) from your blood. It also causes the liver to release less glucose. These two effects together create dangerously low glucose levels in your blood. This condition is called hypoglycemia</em>

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.
