In the electron transport system
antoniya [11.8K]

Answer:

A. NADH and FADH2 both donate electrons at the same location.

Explanation:

In the respiratory chain, four large protein complexes inserted into the mitochondrial inner membrane transport NADH and FADH₂ electrons (formed in glycolysis and the Krebs cycle) to oxygen gas, reducing them to NAD⁺ and FAD, respectively.

These electrons have great affinity for oxygen gas and, when combined with it, reduce it to water molecules at the end of the reaction.

Oxygen gas effectively participates in cellular respiration at this stage, so its absence would imply interruption of the process.

NADH and FADH₂ electrons, when attracted to oxygen, travel a path through protein complexes, releasing energy in this process.

The energy released by the NADH and FADH₂ electrons in the respiratory chain in theory yields <u>34</u> <u>ATP</u>, however, under normal conditions an average of 26 ATP molecules is formed.

If we consider that these 26 molecules are added to the two ATP formed in glycolysis and two ATP formed in the Krebs cycle, it can be said that cellular respiration reaches a maximum yield of 30 ATP per glucose molecule, although theoretically this number was 38 ATP per glucose molecule.

A lamp that plugs into a wall socket draws energy which flows through a thin wire in the bulb causing it to glow. What energy tr
Softa [21]

Answer:

Electrical>thermal>light

Explanation:

Electrical energy refers to energy which is gotten from potential energy. This energy source could be a wall socket.

Thermal energy on the other hand refers to internal energy of a system where temperature is constant.

Light energy is made up of photons which transmits electromagnetic radiation which move in waves and become visible to human eye.

Therefore, the energy transformation taking place according to the question is option D.

How do tussock moths obtain energy in cellular respiration?
s2008m [1.1K]
Tussock moths obtain energy by cellular resporation by the oxidation of food they consume. The food they consume is oxidised to synthesize special type of phosphate which is then stored as energy. The energy is utilised by their cells whenever needed.
