Answer:

The correct answer would be C. Electron transport and chemiosmosis

Electron transport chain (ETC) refers to the series of electron carriers present in the internal membrane of the mitochondria. The electrons from NADH and FADH₂ are carried through the ETC and are finally accepted by water.

Some of the energy of these high energy electrons is used to pump protons into inter-membrane space. It leads to the formation of a proton gradient across the inner membrane.

This gradient is used by the enzyme ATP synthase to phosphorylate ADP into ATP which is termed as chemiosmosis.

ETC and chemiosmosis produced most of the ATP during cellular respiration.

Glycolysis only produces two ATP and two NADH. Krebs cycle produces 6 NADH and 2 FADH₂ from one glucose molecule.

These molecules of  NADH and FADH₂ undergo ETC and chemiosmosis to produce ATP.

6) How does an offspring of a mushroom or mold (asexual reproduction) compare to its parent?
Verizon [17]

A mushroom or a mold commonly reproduces asexually by the formation of spores. Spores are produced in the sporangium through mitosis involving only one parent. They are released from the parent and germinate into new a mushroom or a mold. The offspring are genetically identical to that parent because their formation do not involve meiosis and fertilization. Spores allow fungi to expand their distribution and colonize new environments.

Contrast the electron transport chain in photosynthesis with the one in cellular respiration by identifying sources of the high-
nlexa [21]

Respiration:

The respiratory chain detailed here is that of mammalian mitochondria:

NADH → NADH dehydrogenase → ubiquinone (coenzyme Q10) → coenzyme Q-cytochrome c reductase → cytochrome c → cytochrome c oxidase → O2;

succinate → succinate dehydrogenase → ubiquinone (coenzyme Q10) → coenzyme Q-cytochrome c reductase → cytochrome c → cytochrome c oxidase → O2.

It consists of the following elements:

The high transfer potential electrons of NADH are transmitted to coenzyme Q10 (ubiquinone) by NADH dehydrogenase, or complex I. Reduced coenzyme Q10 is ubiquinol Q10H2.

The electrons with a high succinate transfer potential are transferred to coenzyme Q10 by succinate dehydrogenase, or coenzyme II, also giving ubiquinol Q10H2.

Ubiquinol Q10H2 transfers its electrons to two cytochromes c under the action of coenzyme Q-cytochrome c reductase, or complex III.

Four cytochromes c each transfer their electron to an oxygen molecule under the action of cytochrome c oxidase, or complex IV. Two molecules of water are formed.

Each of these four respiratory complexes has an extremely complex structure partially included in the internal mitochondrial membrane. Apart from the complex II, they are proton pumps. The electrons circulate between these structures on liposoluble or hydrophilic electron transporters depending on the case.

Photosynthesis:

Photophosphorylation is the equivalent, for photosynthesis, of oxidative phosphorylation for cellular respiration. It constitutes the "light phase" of photosynthesis, that is, it groups together light-dependent reactions.

In plants, photophosphorylation occurs in the membrane of thylakoids, within chloroplasts:

H2O → photosystem II (P680) → plastoquinone → cytochrome b6f complex → plastocyanine → photosystem I (P700) → ferredoxin → ferredoxin-NADP + reductase → NADP +;

cyclic photophosphorylation: (ferredoxin →) plastoquinone → cytochrome b6f complex → plastocyanine → photosystem I (P700) → ferredoxin (→ plastoquinone).

Contrast:

<u>What he has in common is:</u>

*The sequence of several complex membrane proteins transporting electrons.

*The conversion of DNA into ATP.

<u>The differences</u> are in the transport proteins themselves, as well as the direction of H + flux (to the cytoplasm for photosynthesis, and to the mitochondrial matrix in respiration).
