Starting with pyruvate to make acetyl-CoA and continuing into the citric acid cycle, and oxidative phosphorylation, how many ATP can be made from 1 molecule of pyruvate

Answers

Answer:

The correct answer is - 15 ATPs.

Explanation:

Cellular respiration (aerobic) is the process that involves glycolysis, oxidative decarboxylation, citric acid cycle and oxidative phosphorylation or ETS to breakdown one molecule of glucose in order to generate energy in ATPs. Pyrivate is the end product of glycolysis and it is go to form acetyl CoA.

One molecule of pyruvate genrates 1 molecule of FADH2, four molecules of NADH, and 1 molecule of ATP during oxidative decarboxylation and citric acd cycle. During the oxidation in the electron transport system there is 4 molecules of NADH2, 1 molecule of FADH2, and 12 (4×3) ATP molecules, respectively by oxidation in the electron transport system (ETS).

Thus, there would be 15 molecules of ATPs produce by one molecule of pyruvate.

C. Skeletal muscles are used to move large body parts. D. Skeletal muscles are attached to the bones. Please select the best answer from the choices provided. A B C D

Answers

Answer:

A. Skeletal muscles control involuntary body functions.

Explanation:

Skeletal muscle is also known as voluntary muscle and it can be defined as a type of muscle connected with the skeleton by tendons, so as to form a mechanical system that enables the movement of the limbs and other body parts with respect to another.

Generally, skeletal muscles are only found in vertebrates.

Skeletal muscles doesn't control involuntary body functions, instead it controls voluntary body functions such as the movement of body parts.

In conclusion, an example of a muscle responsible for controlling involuntary body functions is cardiac muscle.

Where is amyglada located in a brain ? How does it function ?​

Answers

Short Answer: The amygdala is located in the brain and its functions are related to emotional learning.

Explanation

The amygdala is a brain structure located in the temporal lobe of the brain. Its functions are related to the emotional system of the brain, and memory. In addition, the amygdala has been shown to influence the emotional learning process. The amygdala is mainly responsible for the formation and storage of memories associated with emotional events, so external sensory stimuli reach the basolateral group of the amygdala, where associations are formed with memories of the stimulus (mainly related to fear).

<< Read Less

Answers

Answer:

Here's a better answer.

There are multiple lines of evidence that provide support for common ancestry and evolution; this would be homologous features of anatomy and embryology and fossil records.

In comparative anatomy, there are many similarities between species because all life is related. Homology is similarities seen because of the ancestry of features or genes in an organism. Similarities can show descent from common ancestors and similarities can be seen in body structures, development, and DNA. Homologous structures are similar traits found in two different species that are the result of having a common ancestor. These structures are similar but may have different functions. An example of this might be the homologous structures in the limbs of humans, cats, whales, and birds. And then there are analogous structures, which similarly is that the structure of different species are similar because the trait is advantageous, not because they are related. An example of this is sharks and dolphins having similar fins. Along with anatomy is Embryology. Different species can have similar embryos because they come from a common ancestor. They may start with the same developmental plan but change drastically as they grow up. An example of this is seen in the early stages of development between fish and chicken embryos.

Next up, the fossil record provides evidence that supports common ancestry and evolution.  The fossil record provides us with visual evidence for evolution. The fossil record directly allows us to pinpoint if there are any similar structures amongst organisms and see if there are any vestigial structures from ancestors that remain in organisms that still roam today. The fossil record depicts evolutionary change over the past four billion years, which can be seen through transitional forms, increasing complexity of life, and geographical distribution. Transitional forms are fossils that show intermediate states between an ancestral species and its evolutionary descendants. Increasing complexity is seen as life on earth becomes more complex. That and geographic distribution which has been studied closely and found that the continents have moved over time and that the fossil record reflects this movement. Fossils of different animals can be found on different continents around the world due to continental drift.

Explanation:

The various pieces of evidence that support common ancestry are homologous organs, fossil records and embryological studies.

What is common ancestry?

The phrase "common descent" in evolutionary biology refers to a particular group of species' shared ancestry. The creation of new species from an original population is a component of common descent. Two creatures are considered to be closely related if they have a recent common ancestor.

In contrast, molecular genetic techniques can also be used to establish shared ancestry from a single universal ancestor of all living things. Natural selection and other factors, such geographic isolation, are considered to have contributed to many speciation episodes during this development from a universal common ancestor.

According to the common ancestry idea, every living thing descended from a single progenitor. Hence, the Theory of Common Descent contributes to our understanding of why traits in species living in different geographic regions vary, why some traits are highly conserved across broad animal classifications (such as vertebrates or tetrapods), why seemingly unrelated species (such as birds and reptiles) share hereditary physical and genetic traits, and why successfully adapted organisms typically have more offspring.

Therefore, embryological studies, fossil studies and homologous organs can help in the study of common ancestry.

The term bycatch or incidental catch refers to ________. non-target species that are caught along with commercial species species harvested for industrial purposes species raised in aquaculture settings species caught as part of traditional fisheries krill and other shellfish

Answers

Answer:

The correct answer is ''non-target species that are caught along with commercial species''

Explanation:

Bycatch refers to bycatch organisms that are not targeted by the fishery. Occurs inadvertently in fishing gear, all fisheries have some unwanted bycatch. Species with little or no commercial value, juvenile stages, or discarded gravid females of the target species (s) are generally included here. These incidental catches can be marginal when fishing is carried out with selective or very substantial gear, when the gear used indiscriminately catches everything that comes along its route. In marine fisheries, it causes injury or death to mammals, birds, turtles, fish, elasmobranchs, and invertebrates.

There is an issue with this artificial selection because the genetic variability is reduced when we do again and again the artificial selection.

Blood pH is sensed by cells known as chemoreceptors that send information about blood pH to the brain via cranial nerve 9 and 10. In order to correct changes in pH, the ventral respiratory group sends signals to the diaphragm to adjust its rate of contraction. These signals are sent via the phrenic nerve. What serves as the effector in this example

Answers

Answer:

The correct answer is - The diaphragm.

Explanation:

If there is a response to stimulation if a bodily tissue or organ becomes active and those of the autonomic system involves two neurons, not single neurons like motor pathways of the somatic nervous system.

In this case, the diaphragm is the organ that gets the signal in order to correct or adjust the rate of contraction in response to changes in pH level, Hence, the diaphragm is the organ that is the effector in this case.
