<span>off the top of my head i would have to say the </span>light-independent reactions<span> of </span>photosynthesis<span> are </span>chemical reactions<span> that convert </span>carbon dioxide<span> and other </span>compounds<span> into </span>glucose<span>. These reactions occur in the </span>stroma<span>, the fluid-filled area of a </span>chloroplast<span> outside of the </span>thylakoid membranes<span>. These reactions take the products (ATP and NADPH) of light-dependent reactions and perform further chemical processes on them. There are three phases to the light-independent reactions, collectively called the </span>Calvin cycle<span>: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration.</span>

The correct sequence for aerobic metabolic breakdown of glucose is
Luba_88 [7]

Answer:

a. glycolysis—preparatory reaction--cirtric acid cycle--electron transport system

Explanation:

  • Glycolysis is the first stage of cellular respiration that occurs in the cytoplasm of the cell. During glycolysis one 6 carbon glucose is converted into two molecules of 3 carbon pyruvic acid or pyruvate.
  • In the preparatory reaction, the pyruvate converted into a two-carbon molecule called acetyl CoA. In this reaction, a carbon dioxide molecule is released and a molecule of NADH is released.
  • The citric acid cycle begins with the reaction of the acetyl CoA with a four-carbon molecule in the mitochondrisl matrix. It goes through a cycle of reactions regenerating the four-carbon starting molecule. ATP, NADH and FADH₂ are produced.
  • The electron transport system is the terminal step of aerobic respiration that operates on the inner membrane of the mitochondria. Reduced coenzymes NADH and FADH₂ move along electron transport system release high-energy electrons and produce ATP.
