A mutation in human ATPase 6, which corresponds to E. coli subunit a, from leucine to arginine at position 156 may allow the mov

Answer:

H+ protons will not be delivered from the cytoplasm towards the extracellular side of the cell membrane

Explanation:

ATP synthases are enzymes that catalyze the hydrolysis of phosphate bonds in the adenosine triphosphate (ATP) or the formation of ATP from adenosine diphosphate (ADP) and phosphate. The hydrolysis of ATP produces the rotation of a ring composed of six or more structurally different ATPase C subunits. The rotation of this ring enables the delivery of H+ protons towards the extracellular membrane surface and this gradient is used to generate energy by producing ATP. In consequence, when the ATPase ring can not move, H+ will accumulate in the cytoplasm, the proton gradient through the membrane will not occur, and ATP will not be produced.

SVEN [57.7K]

Answer:

increase

Explanation:

As water and ions are lost through exercise, overall blood volume can decrease. To maintain adequate blood volume and blood pressure, renin is secreted to help in the conversion of angiotensin I to angiotensin II. This will cause vessels to constrict and sodium and water to be retained by the kidneys.

Discuss the steps that the animals cells breaks down glucose to produce usable energy
tigry1 [53]

Answer:

As the heart pumps, glucose is carried in the bloodstream to cells all over the animal’s body. Oxygen which enters the animal’s body through its respiratory system (lungs, gills, skin, or exoskeleton) is carried by its transport system (blood for many animals to every animal cell. Once the glucose and oxygen arrive in the cell they can go through a chemical reaction. Glucose reacts with oxygen to produce carbon dioxide and water. Cells transform the chemical energy in the glucose molecules into energy for cell functions, motion energy, and heat. Because of cellular respiration, muscle cells have access to the energy necessary to contract or relax in response to a signal from the brain sent through nerve cells, so muscles can contract or relax enabling the animal to move. During cellular respiration, energy is released in the cell to enable the work of the cell to occur. The atoms found in glucose are rearranged into carbon dioxide and water and are no longer needed by the cell so they are considered waste products. Cells have to get rid of unwanted waste products. Carbon dioxide and water move out of cells and into the blood. The blood carries the carbon dioxide and water to different places in different animals (the lungs, gills, skin, kidneys, or exoskeleton) where they are released into the environment. Animal movement we observe at the macroscopic scale is possible because cellular respiration is happening at the atomic-molecular scale.

Which graph most likely shows an ecosystem that has underwent a primary succession event during the observation period?
gayaneshka [121]
Hello! The answer is D

Primary succession is an event that occurs when an ecosystem is devoid of all organisms and a slow growth of the ecosystem is observed until it reaches a climax population. The most common example of a primary succession is the land development after a volcano eruption. 

In graph D a slow increase in the number of individuals is observed until the graph reaches a maximum, that is called the climax population. This is why this graph shows an ecosystem that has undergone a primary succession during the observation period.

A plant from F1 generation of problem 3 is crossed with a plant from a true breeding dwarf lineage. What are the hw o types and
weqwewe [10]

Answer:

Tt, Tt, tt, tt.

Phenotype: two tall and two dwarfs

Explanation:

The F1 generation will be the crossing of True tall and true dwarf plants to give all tall plants. Kindly note that the genotype for true tall plants is represented by TT, and the genotype for true dwarf plants is represented by tt. The crossing of the two true tall and true short gives Tt, Tt, Tt, Tt; in which the phenotype = all the plants are tall.

If the F1 generation is crossed with the true dwarf plants that is; Tt with tt. It gives us:

T t                          t t.

Tt, Tt, tt, tt. So, the phenotype is two tall and two dwarfs and the genotype is 2 of Tt and 2 of tt.
