Answer:
When ATP is broken down to ADP
Explanation:
Energy is released from a molecule of ATP when the substance is broken down to ADP
ATP is the energy currency of a cell. It is called Adenosine Triphosphate
When a phosphate is removed, it become ADP - Adenosine Disphosphate.
In like manner, the breaking down releases inherent chemical energy and converts it to other forms of energy.
This is how the body system derives sufficient amount of energy for every of its activities.
When an organism undergoes cellular respiration, this is the process that is in play to release energy needed for the body to function
Isotonic since in a hypertonic solution the cell would shrivel up and in a hypotonic solution it would lyse (burst).
<span>A patient is admitted with lower abdominal pain and nausea. the nurse performing the initial assessment notes that the patient's abdomen is distended and firm, and hypoactive bowel sounds are present. the patient has not had a stool for 3 days. the nurse will contact the provider, who will most likely perform diagnostic tests.</span>
Options for part A are as follows:
A) A mutation in the operator sequence
B) A mutation in the lac-Z gene
C) A mutation in the lac-Y gene
D) A super repressor mutation
Answer:
The correct answer:
Part a - A mutation in the operator sequence
Part b - It ensures that a cell dedicates resources to the production of enzymes involved in lactose metabolism only when lactose is available in the environment
Part C. true.
Explanation:
part a:
If there is a mutation in the operator sequence leads to prevent binding of the repressor which leads to allowing constitutive expression of the genes various conditions.
part b:
The biological role of the lac operon makes sure that the cell dedicates resources to the production of enzymes involved in lactose metabolism only when lactose is available in the environment
Part c:
RNA polymerase cannot transcribe the structural genes due to the repressor binds to the lac operator, therefore, the proper function of the lac operon is possible when the placement of the operator sequence between the promotor and the structural genes.
The correct answer is D. Homeostasis and transport of molecules
Explanation:
The diagram presented shows the movement of glucose from outside the cell to inside it. Also, this diagram illustrates this process occurs through the cell membrane and there is a higher concentration outside the cell.
This complex process illustrates the transport of molecules in the cell, which refers to a mechanism that allows molecules and substances to move in and out of a cell. Moreover, this process implies molecules (in this case glucose) move to one area with a lower concentration to preserve equilibrium as shown by the diagram. Additionally, this equilibrium is part of homeostasis which is a set of mechanisms to main an equilibrium in the cell, including appropriate levels of glucose and other substances.
