The first question is B. false, The answer to the second question is stolon.
Answer:
B. glucose – NADH – electron transport – O2
Explanation:
This is the sequence from glycolysis in which glucose molecules are split down to pyruvate, to oxidative phosphorylation.
During this process the electrons are released from glucose molecule as it is oxidised multiple times as pyruvate, and other molecules formed subsequently in Kreb's cycle, until the oxidative phosphorylation is reached .
The makes the carrier molecules to be reduced.Thus NAD→NADH,FAD→FADH .
The electrons from above are transferred in hydrogen atoms to matrix by these co-enzymes.Where the H is split to electrons and protons.
The electrons for the ETC, produce the PMF for transporting protons into the intramembrane space.
The concentration of protons generated the electrochemical gradients which is needed to produce energy for for phosphorylation of ADP with Pi to form ATP by ATpase synthase.
The electrons moves as chain,and this is finally accepted by oxygen as the final electron acceptor.
You can easily remember it because the scientific name of leech is Hirudinaria. So it secretes anticoagulant named hirudin. Which help it to feed blood longer
The energy for ATP synthesis comes from organic molecules (such as carbohydrates), or from sunlight, or from inorganic electron donors. We can classify organisms according to their source of energy and organic carbon:
<span><span>heterotrophs – get energy and organic carbon from metabolism of pre-existing organic compounds (food)</span><span>photoautotrophs – use energy from sunlight to make ATP and their own organic carbon compounds from carbon dioxide chemoautotrophs</span><span> – use energy from inorganic chemicals to make ATP and their own organic carbon compounds from carbon dioxide</span></span>
Metabolic pathways carry out reactions that capture energy from these various sources (organic compounds, sunlight or chemicals) and couple them to synthesis of ATP from ADP.
