Answer:
Glycolysis evolved before Kreb's cycle and Electron Transport chain. This view is supported by following facts:
- Glucose cannot enter the mitochondria and it needs to be broken down into pyruvate in the cytosol by the process of glycolysis.
- Pyruvate then forms acetyl CoA that enters the mitochondria where it undergoes Kreb's cycle.
- The Electron transport Chain occurs by passing of electron and finally donating it to the electron acceptor oxygen. The molecules of NADH produced in the preparatory phase of glycolysis provides the electron for electron transport chain.
- Thus Glycolysis must have evolved before Kreb's Cycle and Electron Transport Chain otherwise the raw materials for both the processes would not have been available.
Answer: B. From the sun.
Most producers absorb energy from the sun.
Answer:
Reductionism
Explanation:
Reductionism is a philosophical theory used to explain different phenomena from simpler phenomena. This idea represents a useful methodology to understand complex processes, and it is widely used in molecular biology and genetics research fields
