The ATPase Synthase Complex Q12.1: 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
Biology
1 answer:
sergey [27]3 years ago
6 0

Answer:

1 H is consumed in exchanging the synthesized ATP in mitochondria with ADP in cytosol by adenine nucleotide translocator (ANT).

Explanation:

The electrons from NADH and FADH2 are transported in electron transport chain through various complexes that act as electron transporter, to oxygen. In this process, the pumping of protons from mitochondrial matrix to intermembrane space causes a concentration gradient and hydrogen ions diffuses out of matrix space through ATP synthase causing the production of ATP.

          3 H are enough to pass through ATP synthase for the phosphorylation of ADP to produce ATP. 1 H or 25% of energy yielded from electron transfer is required to exchange the matrix ATP with the ADP in intermembrane space by adenine nucleotide translocator (ANT). This process provides continuous supply of ADP to mitochodaria and ATP which is exported to cytosol is utilized by cell to perform various functions. There will be no ATP production in mitochondria without ADP. So 4 H are required for 1 ATP production.

1 H for importing ADP to mtichodaria + 3 H for phosphorylation of ADP to ATP

Why are the processes of oxidation and reduction important to cellular respiration?
DiKsa [7]

Answer:

During aerobic respiration, oxygen is reduced, donating an electron to hydrogen to form water. The entire process of cellular respiration oxidizes glucose. This produces the majority of the energy released in cellular respiration

Humans and baboon have noses with nostrils that face downward, but many other primates have noses with nostrils that face out to
Zepler [3.9K]

Answer:

a shared derived trait.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.

Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, weight, handedness, freckles, curly hair, hair color, blindness, complexion, height, etc.

All humans and baboons are created having noses with nostrils underneath i.e facing downwards but other primates such as platyrrhines have their nostrils facing sideways (face out to the side). Also, humans and baboons shared close similarities with each other when compared than they share with the primates having a outward-facing nostrils.

This ultimately implies that, both humans and baboons sharing the downward-facing nostril orientation is an example of a shared derived trait.

A shared derived trait can be defined as a trait or characteristic that is shared between two lineages and subsequently evolves leading up to a clade, which is a distinguishing feature from other species.

According to the fossil record found in sedimentary layers what conclusion can be made? What can you tell about each layer compo
luda_lava [24]

Explanation:

To unravel and understand the importance of fossils in rocks, the principle of fossil and fauna succession gives an amazing insight.

The principle of fossil and fauna succession suggests that "fossils and fauna succeed one another in a defined pattern".

Using this principle we can place sedimentary rock layers into their perfect place and stratigraphy.

Fossils are good indicators of the age of the strata in a sequence based on the principle of fossil and fauna succession.

They are best used in relative dating of rocks.
