6. How did Darwin think plants and animals had originally come to the galapagos islands?||
ycow [4]
Perhaps our first association with the word "Galapagos" is the name "Darwin." Darwin's visit to the Galapagos Islands had a resounding impact on the formation of his Theory of Natural Selection.

A rather unmotivated and failing medical scholar, Charles Darwin accompanied Captain Robert Fitzroy as a travel companion and naturalist on the HMS Beagle. His book the Voyage of the Beagle is an account of his worldwide journey.

When setting off from England in 1831 for a five-year voyage, Darwin had little ambitions for groundbreaking scientific research. After surveying the coasts of South America, the ship stopped over in the Galapagos Islands.

During his visit to the islands, Darwin noted that the unique creatures were similar from island to island, but perfectly adapted to their environments which led him to ponder the origin of the islands' inhabitants.

Among those that struck Darwin so greatly were the finches that are now named in his honor. Darwin would later base some of his thought from the supposing that these finches were all descendents of the same lineage.

Years later in 1859, Darwin finally consolidated all of his observations into his famous book On The Origin of Species, drastically and controversially altering the scientific view on the biological origins of life. Hope this helps! Mark brainly please!

For each molecule of glucose that is processed by glycolysis and the citric acid cycle, what is the total number of nadh fadh2 m
elena-14-01-66 [18.8K]

12 is the total number of NADH FADH2 molecules that will be produced.

In each citric acid cycle, one molecule of FADH2 is formed during the conversion of succinic acid to fumaric.

The CAC is called a cycle because the starting molecule, oxaloacetate is regenerated at the end of the cycle.

It is also known as Krebs cycle. This is actually a part of a huge process called cellular respiration. The citric acid cycle captures the energy stored in the chemical bonds of acetyl CoA (processed glucose) in a step-by-step process, trapping it in the form of high-energy intermediate molecules.

NADH:- It is an energy shuttle that delivers high energy electrons to the electron transport chain where they eventually get to power the production of 2 to 3 ATP molecules.

FADH:- This is another energy shuttle that carries high energy electrons to the electron transport chain, where they will ultimately drive production of 1 to 2 ATP molecules.

Which describes the process of fermentation?
pav-90 [236]

Explanation:

<u>anaerobic process that restores NAD+ supply</u>

<u></u>

Within cells, aerobic respiration may not occur due to several factors:

  • - a lack of inorganic,  final electron acceptors
  • -incomplete or lack of a complete electron transport system
  • -missing genes for enzymes within the Kreb's cycle

Thus, they utilize other means for the generation of energy in the form of ATP and to replenish NAD+ an oxidized form of NADH, the main electron carrier in glycolysis.  Pyruvate is produced  in the cytoplasm via glycolysis- it is also used as an electron acceptor in a process called fermentation.

Further Explanation:

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

  • Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
  • The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
  • The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.
