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.
<span>The answers are visual spectrum and pupil. The visible light spectrum is a narrow band of frequencies ranging from 390 to 780 wavelengths long. These wavelengths are detectable by the eye and the different length corresponds to different colors.
The pupil determines how much light can enter the eye. It dilates and constricts depending on the amount of light available.</span>
The role of 3tc in inhibiting hiv reproduction is to interfere with enzyme trancriptase since it has a similar shape to the c nucleotide of DNA.Reverse trancriptase pick up 3tc molecule which led to termination of DNa further thus block reproduction of HIV.
