What does Glycolysis and ETC take in (whats their input) and take out (whats their output)?

Biology
1 answer:
levacccp [35]3 years ago
5 0

Answer/Explanation:

Glycolysis takes in one molecule of glucose (6C), and produces two molecules of pyruvate (3C). This requires the energy from the conversion of 2 molecules of ATP to 2 molecules of ADP.

This process releases energy in the form of 4 molecules of ATP (from ADP) and 2 molecules of NADH (from NAD+)

The electron transport chain (ETC) uses 1 molecule of NADH and 1 molecule of FADH2 (produced in the Kreb's cycle, the stage between glycolysis and the ETC), as well as one molecule of oxygen.

The ETC generates NAD+, 32 molecules of ATP, as well as water as a byproduct.

1. The answer is "<span>the energy required to start the reaction".

</span>This energy is called as activation energy of the reaction. If the activation energy is high, reaction is slow. Enzymes help to carry out the reaction by a new path by reducing the activation energy. But the energy of reactants and the products remain as same as without enzyme.

2. The answer is "reaction in cells would be too slow to sustain life<span>".

</span>If the activation energy is very high for the reaction, then that reaction will be very slow and will require more time<span> to complete the reaction. Then survival is very low. Hence, the roll of enzymes is very important to sustain life.</span>

Which of the following events can result in inheritable genetic variations in organisms
Svetlanka [38]

The right answer is B.

The answer B is the only proposition which specified at which stage the event must occur, in fact, the meiosis.

Meiosis is a characteristic division of reproductive cells that can generate gametes to form new species (desendence). So if a mutation occurs at this time (such as recombinations) it will inevitably be inherited.

Explain how Ab diversity is generated
inysia [295]

Explanation:

After repeated stimulation by antigen, B cells can make antibodies that bind their antigen with much higher affinity a process called affinity maturation. ... Thus, antigen stimulation greatly increases the antibody arsenal. Antibodies are proteins, and proteins are encoded by genes.

What do many scientists believe about the purpose for asteroids.
katovenus [111]

Answer:

Various scientists describe asteroids in different ways:

  • Some scientists consider it to be rocks which orbit around the sun.
  • Other consider it to be small planets.

The majority of the scientists agree that asteroids might have come into existence at the time of solar formation. The parts which broke down during the formation of the solar system resulted in the formation of asteroids.

<u><em>Scientists believe that asteroids might not have a major function in the universe but studying them would be of great benefit. This is because as they are parts broken from the solar system, exploring them will let us know about some unknown features of the other solar system bodies. </em></u>
