Is ATP used for long term storage?

Answers

Answer:

Explanation:

ATP is not used for long term storage.

ATP will release or give off energy when it releases a phosphate molecule. Since a cell can add or subtract a phosphate group, it has a way of storing and releasing energy. Most cells have only a small amount of ATP. It can't be used to store energy for long periods of time. These ATP stores last only a few seconds after which the breakdown of PC provides energy for another 5-8 seconds of activity. Combined, the ATP-PC system can sustain all-out exercise for up to 10-15 seconds and it is during this time that the potential rate for power output is at its greatest. These ATP stores last only a few seconds after which the breakdown of PC provides energy for another 5-8 seconds of activity. Combined, the ATP-PC system can sustain all-out exercise for up to 10-15 seconds and it is during this time that the potential rate for power output is at its greatest. Hence, ATP cannot be stored easily within cells, and the storage of carbon sources for ATP production (such as triglycerides or glycogen) is the best choice for energy maintenance. Lipids are molecules that can be used for long-term energy storage. Most cells have only a small amount of ATP. It can't be used to store energy for long periods of time. It is more efficient for a cell to keep a small supply of ATP. Cells can regenerate ATP from ADP as needed by using the energy in carbohydrates like glucose. The ATP molecule is just like a rechargeable battery. When it's fully charged, it's ATP. When it's run down, it's ADP. However, the battery doesn't get thrown away when it's run down–it just gets charged up again. Living organisms use two major types of energy storage. Energy-rich molecules such as glycogen and triglycerides store energy in the form of covalent chemical bonds. Cells synthesize such molecules and store them for later release of the energy. Monosaccharides
Monosaccharides contain just one sugar unit, so they're the smallest of the carbohydrates. (The prefix "mono-" means "one.") The small size of monosaccharides gives them a special role in digestion and metabolism. In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. ... When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.

Answers

Complete question:

Suppose a graduate student is studying a loss-of-function mutation in the mouse gene zigzag. Whereas wild type mice have straight tails, zigzag mutant mice have tails with two sharp kinks, so that the tail looks like the letter Z. To determine how the zigzag phenotype is inherited, he performs the crosses listed in the first column of the table below, using parents from true-breeding lines. Three possible sets of results from these crosses are shown. Determine the mode of inheritance of the zigzag gene that would yield each result set.

Mode of inheritance Options:

cytoplasmic-linked recessive inheritance, maternal effect inheritance, genomic imprinting (paternal allele is inactive), genomic imprinting (maternal allele is inactive), x-linked recessive inheritance

Note: You will find the table in the attached file

Answer:

Set A: X-linked recessive inheritanceSet B: maternal effect inheritanceSet C: genomic imprint (paternal allele is inactive)

Explanation:

SET A:

X-linked recessive inheritance: This pattern refers to a recessive mutated allele that expresses the abnormal character and is linked to the X chromosome.

Cross 1: zig zag female x wild type male

Parental) Xz Xz x X+Y

F1) Phenotype---> 50% zigzag (all males) ; 50% wild type (all females)

Genotype---> ½ X+ Xz ; ½ Xz Y

Cross 2:

Parental) X+ Xz x Xz Y

F1) Phenotype---> From the whole progeny: 25% wild type females ; 25% wild type males ; 25% zigzag females ; 25% zigzag males - 50% wild type animals + 50% zigzag animals

Genotype---> ¼ Xx Xz ; ¼ Xx Y ; ¼ Xz Xz ; ¼ Xz Y

Cross 3: wild type female x zigzag male

Parental) X+ X+ x XzY

F1) Phenotype---> 100% wild type animals (50% females + 50% males)

Genotype ---> ½ X+ Xz ; ½ X+ Y

Cross 4:

Parentals) X+ Xz x X+Y

F1) Phenotype---> From the whole progeny: 50% wild type females ; 25% wild type males ; 25% zigzag males

Genotype ---> ¼ X+ X+ ; ¼ X+ Xz ; ¼ X+ Y ; ¼ Xz Y

SET B:

Maternal effect: Refers to the influence of the “environment provided by the mother” on the progeny phenotype. The mother´s genotype directly determines the progeny phenotype. The progeny genotype is irrelevant, as well as the father´s genotype or phenotype. This means that no matter what is the genotype of the offspring, all of them will express the same phenotype as their mother. This effect is commonly seen in insects, but it might also occur in mammals and plants. A much known experiment about this effect is the one performed on Limnea sp snail.

Cross 1: zig zag female x wild type male

Parental) Xz Xz x X+Y

F1) Phenotype-->100% zigzag animals, due to the female´s phenotype, Xz Xz

Genotype--> ½ X+ Xz ; ½ Xz Y

Cross 2:

Parental) Xx Xz x Xz Y

F1) Phenotype-->100% wild type animals, due to the female´s phenotype, Xx Xz

Genotype--> ¼ Xx Xz ; ¼ Xx Y ; ¼ Xz Xz ; ¼ Xz Y

Cross 3: wild type female x zigzag male

Parental) X+ X+ x XzY

F1) Phenotype-->100% wild type animals, due to the female´s phenotype, X+X+

Genotype --> ½ X+ Xz ; ½ X+ Y

Cross 4:

Parentals) X+ Xz x X+Y

F1) Phenotype-->100% wild type animals, due to the female´s phenotype, X+ Xz

Genotype---> 100% wild type animals

SET C:

Genomic imprint (Paternal allele inactive): Refers to a pattern that characterizes for epigenetically inheritance and for unequally functional paternal and maternal genomes. Males X chromosomes are inactive or imprinted and have a different function from those females X chromosomes. This is a common pattern in some mammals, insects and angiosperms. The paternal allele can not be expressed which causes an unequal contribution to the progeny phenotype.

Cross 1: zig zag female x wild type male

Parental) Xz Xz x X+Y

F1) Phenotype--->100% zigzag animals, because the male´s X chromosome is imprinted or inactive

Genotype--->½ X+ Xz ; ½ Xz Y

Cross 2:

Parental) Xx Xz x Xz Y

F1) Phenotype--->50% wild type animals ; 50% zigzag animals. Due to both the female´s chromosomes, Xx Xz

Genotype---> ¼ Xx Xz ; ¼ Xx Y ; ¼ Xz Xz ; ¼ Xz Y

Cross 3: wild type female x zigzag male

Parental) X+ X+ x XzY

F1) Phenotype--->100% wild type animals, due to the female´s phenotype, X+X+

Genotype ---> ½ X+ Xz ; ½ X+ Y

Cross 4:

Parentals) X+ Xz x X+Y

F1) Phenotype--->50% wild type animals ; 50% zigzag animals

Genotype ---> ¼ X+ X+ ; X+ Y (Wild type)

¼ X+ Xz ; ¼ Xz Y ( zigzag)

The measurement of 45 N represents the magnitude of force in the photograph.

What is force?

Force is defined as a cause which is capable of changing the motion of an object. It causes an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as a direction.Hence, it is a vector quantity.

It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.

The concepts which related to force are thrust and torque .Thrust increases the velocity of an object while torque produces change in rotational speed of an object.
