Which provides long-term energy storage?

Glycogen provides long-term energy storage.

Glycogen is an example of a carbohydrate which is a polysaccharide that acts as a long-term energy storage compound in animals.

<h2>Further Explanation </h2>
  • Living organisms require energy in order to undertake their daily activities such as growth and development, locomotion, gaseous exchange, etc. To do so they obtain nutrients for short-term and long-term energy source.
  • Carbohydrates are the major energy source for living organisms, however, living organisms may use other sources of energy such as proteins or fats when carbohydrates is out of stock or not available.  

Energy source in animals

  • Animals use simple carbohydrates such as glucose obtained from diet for short-term energy sources.
  • These simple carbohydrates may also be stored for future use in the form of glycogen, which makes glycogen a long-term energy source, to be used when need arises.
  • When glucose levels are low in the body hormones in the body trigger the breakdown of glycogen to glucose.
  • Other sources of energy such as proteins and fats are used when carbohydrates storage is depleted, for example during starvation.

Energy source in plants

  • In plants, on the other hand, simple carbohydrates are similarly used as a short term source of energy. Additionally, simple molecules such as glucose are stored in the form of starch for long-term source of energy for the plants.  

<em><u>Why other Choices are incorrect</u></em>:

<h3>Glucagon  </h3>
  • Glucagon is the hormone that increases the blood glucose level to avoid it from dropping below optimum level.
  • The hormone acts on the liver to stimulate the breakdown of glycogen to glucose, a process called glycogenolysis, and the glucose is released to the blood stream.

<h3>Glucose </h3>
  • Glucose is a simple carbohydrate classified as monosaccharides. It acts as the short term source of energy in both plants and animals.
  • It is readily broken down during the process of cellular respiration to yield energy in the form of ATP, which is then used to drive cellular processes.

<h3>Cellulose </h3>
  • Cellulose is an example of a complex carbohydrates known as polysaccharides.
  • It is found in plants cells lining the cell wall of all plant cells which is one of the key distinguishing feature between plant cells and animal cells.

A jogger in July produces large amounts of sweat. Due to this the kidneys change the rate of urine production. Why is this impor
ivolga24 [154]
When it's hot or when the organism starts sweating a lot, this causes an amount of water to be lost from the body. Water is important for the organism to survive and it's absence wi lead to death, therefore Osmoreceptors cells in the hypothalamus in the brain, sends signals to increase the rate of water re-absorption by the kidney. This causes the urine to be of a low volume and more concentrated. This allows enough water to be used by the body as a lot has been lost during sweating.

Most coastal areas on Earth experience two high tides and two low tides every lunar day. What is a lunar day? Our days on Earth
ahrayia [7]

The correct answer is - C) 5:35 PM Friday.

The low tides occur twice in a lunar day, thus they are diurnal. The low tides appear when the Moon is between that point of the planet and the opposite of that point of the planet, thus in between, which is happening twice, on opposite parts of the planet.

Since the lunar day lasts for 24 h 50 m, we should just divide it in two, thus get 12 h 25 m. Than we should add the 12 h 25 to the time when one of the low tides appeared, which is 5:10 AM, so we will get 5:35 PM.

The low tides appear because the Moon is pulling the water upwards with its gravitational pull above the place where it is, so the side parts of the planet have their waters dragged away,thus resulting in the retreating of the water, known as low tide.

Simone is creating a model to track the movement of carbon atoms in an ecosystem. Which statement best explains the role of plan
Mademuasel [1]

Although I cannot see the model for Simone's experiment, I can offer the insight that the most likely role of plants in the model is that they consume the carbon atoms and produce oxygen.

<h3>How do plants affect the carbon in the atmosphere?</h3>
  • Plants are known to have a<u> great effect</u> on the carbon levels of the atmosphere.
  • The correlation is that the more plants are present, the less carbon is free in the air.
  • The reason for this is that plants use carbon dioxide as a substrate to manage the process of photosynthesis.
  • As a by-product, after consuming carbon dioxide and completing photosynthesis, plants release oxygen into the atmosphere.

Therefore, we can confirm that the most likely role of plants in the model created by Simone, is that they will consume carbon atoms in the form of carbon dioxide in order to sustain photosynthesis, which releases oxygen.

Onsidering that gluconeogenesis requires a net input of 4 atp equivalents compared to glycolysis, why would a cell utilize this
Pani-rosa [81]

The process by which organisms create sugars (specifically glucose) from non-carbohydrate precursors is known as gluconeogenesis.

  • The only energy source used by the brain, testes, erythrocytes, and renal medulla is glucose, with the exception of ketone bodies during fasting. There are three highly exergonic stages in glycolysis. Hexokinase, phosphofructokinase, and pyruvate kinase are among the enzymes involved in these additional regulatory stages. In biological processes, both forward and backward reactions are possible.
  • Similar to glycolysis, but with the process going the other way, is gluconeogenesis. Fructose-1,6-bP, glucose-6-P, and pyruvate all undergo fairly spontaneous conversions in the process of gluconeogenesis, which is why these reactions are tightly controlled.
  • For the organism to function properly, energy conservation is crucial. Gluconeogenesis is suppressed when there is an abundance of energy available.

Therefore, gluconeogenesis conserve more energy.
