A.
To find: Whether the given condition “reduced ubiquinone and oxidized cytochrome c” can transfer the electrons to cytochrome c.
Concept introduction:
In the mitochondria, electron transport system is there for the production of ATP. The protons generated will move through a series of electron carriers and respiratory complexes in the ETS. Electron carriers will transfer the electrons, and the respiratory complexes contain multiple individual proteins including transmembrane protein that helps in the passage of electrons.
A.

Answer to Problem 23Q
Explanation of Solution
Respiratory complex is necessary for the transfer of electrons. Cytochrome c reductase complex is lacking in the first condition, and only reduced ubiquinone and oxidized cytochrome c are present. So, the electron transfer does not take place in this condition.

B.

Answer to Problem 23Q
Explanation of Solution
Electron transfer is not possible when both electron carriers are in the oxidized condition. Here, ubiquinone is in the oxidized condition, so it has the ability to gain electrons but is not able to transfer the electrons to cytochrome c. Not only this is the reason, electron transfer can be done in the presence of the respiratory complex, but it is absent in this condition. So, electrons cannot be transferred from the ubiquinone to cytochrome c.
C.
To find: Whether the given condition “reduced ubiquinone and reduced cytochrome c’’ can transfer the electrons to cytochrome c.

C.

Answer to Problem 23Q
Explanation of Solution
In this condition, both the electron carriers are in their reduced state. Here, ubiquinone is in the reduced condition, so it has the ability to lose the electrons but cytochrome c cannot accept the electrons. Hence, the electron flow does not occur in this condition, and therefore, the transferring of electrons from ubiquinone to cytochrome c does not occur.

D.

Answer to Problem 23Q
Explanation of Solution
Ubiquinone is in the oxidized condition, and the electron added to it has high free energy as compared to the electron added to the reduced cytochrome c. The respiratory complex, cytochrome c reductase complex is absent here. Because of these reasons, the electron transfer is not possible in this condition.
E.
To find: Whether the given condition “reduced ubiquinone, oxidized cytochrome c, and cytochrome c reductase complex”can transfer the electrons to cytochrome c.

E.

Answer to Problem 23Q
Explanation of Solution
In the electron transport system, there is a particular pathway for the electron transfer. If the ubiquinone is reduced, cytochrome c is oxidized and the cytochrome c reductase complex is present, then the electron will transfer in the favorable condition.

F.

Answer to Problem 23Q
Explanation of Solution
The cytochrome c reductase is present in this condition but also the electron transfer will not occur here because both ubiquinone and cytochrome c are in the oxidized condition. If both electron carriers are in the oxidized condition, electron flow will not happen. For the electrons to flow through the first electron carrier that is, the ubiquinone, it must be in the reduced state and the other one must be in oxidized condition.

H.

Answer to Problem 23Q
Explanation of Solution
Electron transfer from ubiquinone to cytochrome c cannot occur only if the respiratory complex is present. The reduced cytochrome c has less free energy compared to the oxidized ubiquinone and due to this reason electron transfer will not take place in this condition.

Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form. i The recessive form is a normal protein - in other words, no neurofibromatosis.moovi A typical pedigree for a family that carries neurofibromatosis is shown below.

The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons 9 glycerol A. Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2.
