assuming the system gets 3 atp per nadh and 2 per fadh2, how many atp molecules are produced (ignore any consumption) from the tca cycle alone? (starting at acetyl-coa and ending at oxaloacetate?)

Answers

The TCA cycle generates two ATPs for each glucose molecule (2 acetyl CoA).

The Krebs or citric acid cycle, sometimes referred to as the tricarboxylic acid (TCA) cycle, is the main source of energy for cells and is crucial for aerobic respiration.

Glycolysis and the TCA cycle are both aspects of cellular respiration.

In living things, food materials are broken down during cellular respiration, and the energy that is released is then stored as ATP and utilised for a number of crucial tasks. Carbohydrates are the main respiratory substrate. Glycolysis, the initial stage of cellular respiration, takes place in the cytoplasm of all living things. It can also be found in anaerobic organisms because it doesn't need oxygen to function. The multi-step enzymatic process involves the partial oxidation of glucose and there are produced two pyruvate molecules.

There is a net gain of 2 ATPs during glycolysis.

For an enzyme-catalyzed reaction, when the enzyme is denatured and loses its shape, what is affected?

Answers

Enzymes are biocatalysts. They increase the rate of a chemical reaction and any change in the shape of enzyme due to its denaturation will make the enzyme ineffective and slow down the biochemical reaction.

What is an enzyme?

Enzymes are the biocatalysts which when present in a reaction increases the rate of a biochemical reaction. This increase in the rate of a reaction is possible due to the lowering of activation energy which is required by the reactant molecules to transform into product molecules.

The function of enzyme is dependent upon the ability of an enzyme to bind to its specific substrate, as enzymes show the property of specificity that is they only bind to specific substrate molecules. The loss of an enzyme's three-dimensional structure or any modulation in the structure as a result of denaturation of the enzyme renders the enzyme ineffective. As a result, the biochemical reactions are slowed down to the rates that are not sustainable for life and takes very long time to complete and form product molecules.

Answers

A base analog that can cause A-T > G-C or G-C>A-T transitions.

Thymine's base analog is 5BU. The thymine analog 5BU pairs with Guanine while thymine pairs with Adenine. The bromine atom in 5BU can switch between its keto and enol forms.

During replication, an A-T pair generates an A-5BU pair when 5BU in keto form replaces the thymine. The unusual enol form of 5BU pairs with G in the first mutagenic phase of replication, and then G couples with C in the subsequent replication cycle. Consequently, the change from the A-T to the G-C pair takes place.

Rarely, the 5-BU in enol form can function as a cytosine analog. This causes C to be replaced by 5BU, turning the G-C pair into a G-BU pair, which eventually transforms into an A-T pair during the second replication cycle.

Therefore, 5BU is a base analog that can lead to transitions from A-T to G-C or G-C to A-T.

The researcher's contention that atmospheric carbon dioxide serves as the precursor to photosynthesis, which plants use to create sugars and other organic molecules, is best supported by the assertions.

According to experts, plants with high CO2 levels have thicker leaves, which might exacerbate the consequences of climate change. Scientists studying plants have found that most species do something odd when atmospheric carbon dioxide levels rise: their leaves thicken.

The finding that increased carbon dioxide only boosted plant growth when nitrate, water, & temperature were preserved at normal levels was the biggest revelation from the study.

a. acetylation and lipidation
b. methylation and acetylation
c. glycosylation and ubiquitination
d. methylation and carboxylation

Answers

Correct option  C - methylation as well as acetylation

A DNA molecule is acetylated when an acetyl group is added, and a DNA molecule is methylated when a methyl group is added.

It is generally known that both histone deacetylation and DNA methylation inhibit gene transcription. In contrast, when histones are deacetylated by HDAC, their electrostatic contacts with DNA become stronger, resulting in relaxed chromatin that upregulates transcription.

Histone acetylation and DNA methylation are examples of epigenetic changes. However, histone acetylation is a chemical covalent modification that occurs in proteins as a post-translational modification of histone proteins, whereas DNA methylation occurs at the DNA level.

Histone modification, which includes methylation, phosphorylation, acetylation, ubiquitylation, and sumoylation, is a covalent post-translational modification of histone proteins. These changes to chromatin structure can regulate gene expression.

why are 4 h needed for every atp synthesized and exported by mitochondria, even though only 3 h need to be translocated by the atp synthase complex to synthesize one atp?

Answers

The 1 H+ needed to cotransport the Pineeds must be taken into account in the equation since the ATP synthase activity would stall if there was not enough Pi available.

Because the conversion of ADP to ATP depends on the oxidative processes taking place in the mitochondria, this procedure is referred as oxidative phosphorylation. The final phase of OXPHOS, the ATP synthase, is driven by a continuous proton motive force, which also powers the synthesis of ATP. To cotransport the Pi required for the ATP synthase complex to phosphorylate ADP, the phosphate translocase needs one H+. The 1 H+ needed to cotransport the Pineeds must be taken into account in the equation since the ATP synthase activity would stall if there was not enough Pi available.One FADH2 molecule creates 2 molecules of ATP, while one NADH molecule generates 3 molecules of ATP.

The formation of simple to complex organic molecules leading to emergence of life on the earth occurred in the reducing atmosphere of primitive earth. Such phenomenon was facilitated by
A. absence of carbon.
B. absence of oxygen.
C. presence of nitrogen.
D. presence of hydrogen.​

Answers

Answer:

D. presence of hydrogen.​

Explanation:

The formation of simple to complex organic molecules leading to the emergence of life on Earth occurred in the reducing atmosphere of the primitive Earth. Such phenomenon was facilitated by the presence of hydrogen.

The early Earth was a very different place than it is today. The atmosphere was rich in reducing gases such as methane, ammonia, and water vapor, but it was relatively poor in oxygen. This lack of oxygen, combined with the presence of hydrogen and other reducing gases, provided the conditions necessary for the formation of simple organic molecules.

Over time, these simple organic molecules combined to form more complex molecules, such as proteins and nucleic acids. These molecules eventually gave rise to the first living cells, marking the beginning of life on Earth.

The presence of hydrogen was critical to this process. Hydrogen is a highly reactive gas, and it can easily react with other molecules to form more complex compounds. In the reducing atmosphere of the primitive Earth, hydrogen played a key role in the formation of simple organic molecules, which eventually gave rise to life.

In summary, the formation of simple to complex organic molecules leading to the emergence of life on Earth occurred in the reducing atmosphere of the primitive Earth. This phenomenon was facilitated by the presence of hydrogen, which played a key role in the formation of simple organic molecules and the emergence of life.

This type of phenomenon was facilitated by presence of hydrogen.​

How are simple to complex organic molecules formed on Earth?

Life on Earth arose from the formation of simple to complex organic molecules in the depleting atmosphere of the primitive Earth, which was facilitated by the presence of hydrogen.

The early Earth was a very different place when it compares to today. The atmosphere was rich in reducing gases like methane, ammonia, and water vapor, but it was relatively low in oxygen due to which it combined with the presence of hydrogen and other reducing gases providing the prerequisites for the formation of complex organic molecules.

The presence of hydrogen was critical to the process because it is a highly reactive gas that can readily react with other molecules to form more complex compounds. In the depleting atmosphere of the primitive Earth, hydrogen played a key role in the formation of the complex organic molecules that gave rise to life.
