Where in the body are the majority of triglycerides stored for future energy needs?

Answers

Answer:

Liver or fat cells

Explanation:

The triglycerides plays important role in providing energy and they are the kind of fats that are energy rich. The triglycerides are made of three fatty acid chains and a molecule of glycerol.

The increased amount of triglycerides stores in liver or fat cells. This stored form is used further to provide energy when required. This natural process helps the body during fasting and maintains energy requirements of the body. The hormone glucagon is responsible to use triglycerides.

Answer:

Triglycerides are made up of one molecule of glycerol attached to the three fatty acid chains. In body majority of triglycerides are stored in liver or fat cells. Glucagon is the hormone that is responsible for the storage of triglycerides in liver or fat cells.

Stored triglycerides act as the reserved energy resource which is used when the glucose and glycogen is depleted in the body which are primary energy resources for the body.

To release triglyceride lipase breaks the triglycerides and release the fatty acids in the blood which is used to provide energy to the body.

Many of the terms related to fluid balance sound the same. Can you identify the proper terms for definitions and key information related to fluid and fluid imbalances? For each question, select the correct term or solute.

Answers

Answer:

Que.1

Standard IV solution used as a blood volume expander (0.9% NaCl is commonly used)

HYPERTONIC  ISOTONIC.

Answer- isotonic.

The  standard 0.9 % Nacl solution is isotonic.  A solution is isotonic if it is of  equal solute concentrations with the surrounding environment. Therefore, 0.9 % Nacl solution will not gain or lose fluid via osmosis across its wall.  Rather  its intravenous introduction will be at the same concentration with the  intracelluar fluid  leading to expansion  in volume.

Type of edema in the lower extremities

DEPENDENT INDEPENDENT.

Answer-Dependent

Accumulation of  blood   in body tissues (Oedema) usually  occurs due to  effect of gravity on the body. Gravitational force pulls body fluid towards the extremities and lower part of the body.Therefore fluids accumulates under the skin, trapped  in the veins of leg (especially from prolong standing), feet and hands.  It may also be as  a result of complication from medication, or pregnancy term is called Dependent Oedema. Because it is gravity-related Oedema.

Increases sodium and water retention by the kidneys

RENIN  ALDOSTERONE

Answer-Aldosterone

In condition of lower blood volume, lower salt level or increse blood pressure,one of the compensatory mechanism is the release of hormone Aldosterone from the pituitary gland,  under the influence adreno cortico tropic hormone  The Aldosterone  stimulate the walls of the distal convoluted tubule and collecting duct to increase re-absorption of sodium ions, from the urine, sweat and gut back  into the blood. Water follow by osmosis. This raises the water level of the blood with corresponding increase blood volume, reduction in salt balance and drop in blood pressure.

The main intracellular cation

POTASSIUM MAGNESIUM

Answer:Potassium

This is  the main intracellular cations of the cell. It concentration is maintained by the activities  of sodium-potassium pump along cell membrane. These pump  made of channel  of protein  regulate the movement of potassium ions in and out of the cells. Its positive charge(together with that  some anions)  is responsible  for the   positive charges  in  the intracellular layer.

Fluid sequestration in the body cavities

PITTING EDEMA /'THIRD SPACE ACCUMULATION.

Answer; third space.

The space between adjacent cells may be filled with fluids, that escape from the blood vessels into the interstitial space when there is too much water in the blood,.This fluid  space  is called the third Space. It has no appreciable function.

Que-

Excreted in response to fluid volume overload.

ALDOSTERONE NATRIURETIC PEPTIDES.

Answer. Natriuretic peptides

An increase in blood fluid  volume  usually correspond with the release of  Natriuretic peptides under the in influence of the pituitary gland and the heart in the body. These promotes the loss of  sodium ions by the kidney, with corresponding loss of water by osmosis.Therefore large volume of hypotonic urine containing excreted sodium is produced. This lowers the blood fluid volume,

Que;

Diminished water volume in intracellular fluid and extracellular fluid

DEHYDRATION THIRD SPACE ACCUMULATION.

Answer; Dehydration

Dehydration is depletion of water level of the plasma fluid, due to loss of  fluid from the intracellular  and extracelular fluids cell layers into the surrounding hypertonic medium.The cells shrinks, with loss of the organelles. Hypotension,  confusion also set in.

Que;

Characterized by excess fluid in interstitial and intracellular fluid compartments

DEHYDRATION EDEMA,

Answer.Oedema

The accumulation of fluid in the space between cells(interstitial space) is called oedema.it may be caused by damage to the kidney, liver, to the veins of the legs etc,This damages lead to poor drainage of the blood by the veins leading  to fluid retention.

Que

Occurs when application of pressure over a bony area leaves an indentation

PITTING EDEMA DEPENDENT EDEMA

Answer. Pitting Edema.

Mathematically, Pressure is equal to force over the area where the pressure was applied.(P=F/A). During   accumulation of fluids under  the skin due to oedema; if a pressure is applied on the fluid accumulated area, an indention due to the force  which  was applied will be left momentarily, and gradually disappear. this is called Pitting Oedema.

Cell growth occurs in interphase or mitosis?

Answers

Cell growth occurs in interphase.

The cell cycle is composed of interphase, mitosis, and cytokinesis. It can be described in five steps.

The first three steps of the cell cycle are called the interphase. This is where the cell grows, the cell matures, and where the cell carries out its life function. The fourth step is mitosis and the fifth step is cytokinesis.

The interphase has three stages. These are Gap 1, synthesis, and Gap 2.

Gap 1 or growth 1 - where the cell grows and functions normally. Cell growth is twice its original size.

Synthesis - where cell duplicates its DNA

Gap 2 or growth 2 - where cell resumes its growth in preparation for division.

Three sources of genetic variation are

Answers

THe 3 sources of genetic variation are the following 
- mutation - the changing of DNA Structure
- Lateral gene transfer - the movement of genetic material into unicellar genes.
genetic recombination during sexual reproduction

Three sources of genetic variation are mutation, recombination and gene flow.

What is genetic variation?

Genetic variation is the differences in the genetic makeup of individuals within a population.

The sources of genetic variation are;

Mutation: Mutations are random changes that occur in an organism's DNA sequence.

Recombination: Recombination occurs during meiosis, the process by which gametes (e.g., sperm and egg cells) are formed.

Gene Flow: Gene flow refers to the movement of genes between populations. This occurs when individuals from different populations interbreed and exchange genetic material.
