The sequence by which electrons travel downhill during aerobic respiration. The se sequence has NADH, oxygen chain of transportation of electron, food and NAD.
Respiration (both aerobic and anaerobic) begins with glycolysis in the cytoplasm of a cell;
1 glucose molecule (C₆H₁₂O₆) is converted into 2 molecules of pyruvate in a 10-step process, consuming 2 ATPs and yielding 4 ATPs;
Additionally, 2 NAD+ molecules are reduced to NADH molecules;
In aerobic respiration, each pyruvate molecule then goes through the link reaction, getting converted to acetyl co-A in the mitochondrial matrix, producing 1 CO₂ molecule and 1 reduced NADH molecule;
Acetyl co-A then enter the Krebs or tricarboxylic acid cycle (TCA) where 2 CO₂, 1 ATP, 3 NADH (by reduction of NAD+) and 1 FADH₂ molecules are produced;
The NADH and FADH₂ molecules produced are electron carriers required for the electron transport chain (ETC);
The electron transport chain consists of 4 proteins within the inner mitochondrial membrane which are involved in the production of ATP by oxidative phosphorylation;
The first protein (C1) is responsible for oxidising NADH to NAD+, releasing energy used to generate the proton motive force (PMF) by pumping the protons (H+ ions) into the intermembrane space and the electrons released are transferred to a ubiquinone molecule;
The second protein (C2) is responsible for oxidising FADH₂ to FADH, also releasing energy used to generate the proton motive force (PMF) and, similarly to C1, the electrons released are transferred to ubiquinone;
The third protein complex (C3) transfers the electrons from ubiquinone to cytochrome C;
Finally, cytochrome C transfers these electrons to the fourth complex (C4), where they combine with free protons in the matrix and O₂ to to produce H₂0;
The PMF is then harvested via an ATP synthase protein where H+ flood back into the mitochondrial matrix, and the energy released is used to generate ATP from ADP and Pi;
ATP is now ready for use for bodily processes requiring it.
how can natural disasters hurt the balance between biotic and abiotic elements??? I need an answer soon pleaseeeee!!! I know how it would affect the biotic and abiotic elements but the balance?!?
Answer:
Earthquakes, landslides, volcanic eruptions and natural bush fires all affect the many different ecosystems on our planet. Initially, these disasters negatively affect the biodiversity of wetlands, forests and coastal systems by causing the spread of invasive species, mass species mortality and loss of habitat.

The Process of Cellular Respiration
Cellular respiration is the process of extracting energy in the form of ATP from the glucose in the food you eat. How does cellular respiration happen inside of the cell? Cellular respiration is a three step process. Briefly:
In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis.
In stage two, the pyruvate molecules are transported into the mitochondria. The mitochondria are the organelles known as the energy "powerhouses" of the cells (Figure below). In the mitochondria, the pyruvate, which have been converted into a 2-carbon molecule, enter the Krebs cycle. Notice that mitochondria have an inner membrane with many folds, called cristae. These cristae greatly increase the membrane surface area where many of the cellular respiration reactions take place.
In stage three, the energy in the energy carriers enters an electron transport chain. During this step, this energy is used to produce ATP.
Oxygen is needed to help the process of turning glucose into ATP. The initial step releases just two molecules of ATP for each glucose. The later steps release much more ATP.
The process is of cellular respiration. Cellular respiration is the process through which the glucose in the food you eat is converted into ATP, which is then converted into energy.
What is cellular respiration?
In the first stage, a procedure known as glycolysis breaks down glucose in the cell's cytoplasm.
The pyruvate molecules are delivered to the mitochondria in stage two. The organelles known as the cellular "powerhouses" of energy are called mitochondria
Pyruvate enters the Krebs cycle in the mitochondria after being transformed into a 2-carbon molecule. These cristae significantly expand the area of the membrane where most cellular respiration occurs.
Therefore, The process is of cellular respiration. Cellular respiration is the process through which the glucose in the food you eat is converted into ATP, which is then converted into energy.

Explanation:
Fill in the blank with the correct term to complete the sentence provided. When the valve between the right atrium and right ventricle has an abnormal narrowing, this is known as
(Answer is NOT pulmonary valve or pulmonary stenosis)
Explanation:
if its correct please let me know
A narrowing of the valve between the lung arteries and the lower right heart chamber (right ventricle) is known as pulmonary valve stenosis (pulmonary arteries).
What is an abnormal narrowing in the heart?The valve flaps (cusps) of a constricted heart valve may thicken or stiffen, as a result, the valve's blood flow is decreased.
When that valve narrows, blood cannot flow correctly and aortic stenosis develops, mild to severe cases of the illness are possible.
The left ventricle of your heart has to work harder over time to force blood past the stenotic aortic valve.
Therefore, an abnormal narrowing of the right atrium and right ventricle is due to pulmonary valve stenosis.

Which type of mutation reverses the direction of parts of a chromosome?
Deletion
Duplication
Inversion
Translocation
Answer:
Its "C" Inversion
Explanation:
I took the test and got it correct
Type of mutation reverses the direction of parts of a chromosome is inversion. The correct answer is option C.
What is the basic structure of chromosome ?The chromosomes are thread like structures present in the nucleus and the these chromosomes carry the genetic information in them from one generation to another.
Inversion inverts the structure of chromsome and it basically turns the chromsomes inverted.
Inversion is the process where one arm of the chromosome gets detached from the basic structure and it gets attached in the inverted direction.
This creates multiple copies of DNA turning it into genetic material and one of the X linked recessive disorders is haemophilia in which same type of mutation caused by the chromosome at the 8th position takes place.
Therefore, Mutation that reverses the directions of the part of the chromosome.

Explanation:
True or False: Because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny.
The statement 'because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny' is TRUE. It is natural selection in action.
According to the evolutionary theory proposed by Darwin, natural selection is the mechanism by which species change (evolve) to adapt to particular environmental conditions.
In this case, the microbiome represents an evolutionary adaptive mechanism, thereby natural selection will tend to favor individuals that have a beneficial microbiome.
In consequence, individuals having a beneficial microbiome will have more chances to reproduce and survive (i.e., they have higher adaptive fitness), thereby they also have more chances to pass this adaptive trait to the next generation.
