Why is ATP used as an active energy source over glucose? A. It is more abundant in food sources. B. It releases its energy quick
neonofarm [45]

Answer:

B. It releases its energy quickly in a single reaction.

Explanation:

Adenosine triphosphate (ATP) is an energy carrying molecule in living systems while Glucose is an organic molecule (carbohydrate) that stores a high amount of energy. Glucose is a monosaccharide and the smallest unit of carbohydrate-containing foods we eat. Chemical energy is stored in the chemical bonds that hold the glucose molecule.

However, during the process of cellular respiration, energy stored in glucose molecule is broken down and transferred to ATP, which stores energy between the phosphate bonds of its molecule. The energy in ATP is released to perform cellular activities when the phosphate bond of the last phosphate molecule is broken.

Although the glucose molecule stores way more energy than ATP molecule, the ATP molecule releases its energy quickly in a single reaction. This makes energy readily available for cellular functions. This property of ATP makes it an active energy source over glucose.

Vera_Pavlovna [14]
Dinoflagellates are a type of algae that live in a symbiotic relationship with the coral. The algae are autotrophic, meaning they can convert the energy of the sun into chemical energy that organisms can use. The algae share some of the nutrients they produce with the coral in exchange for coral's protection. 
if the algae die off, the coral loses an important source of nutrients and dies too.

In his attempt to develop a pneumonia vaccine, Frederick Griffith injected mice with various combinations of living and dead bac
n200080 [17]

Answer:

The mice died

Explanation:

In Griffith's experiment, two strains of the same bacteria were used. S strain was smooth because it had a polysaccharide coat. This coat also made it virulent because mouse immune system was not able to destroy it and ultimately the mice died. R strain was rough because it did not have the coat and thus was harmless to mice.

When Griffith injected mice with dead S bacteria and living R bacteria together, the mice died. Live R bacteria had taken up the genetic material or as Griffith called "transforming principle" from the dead S bacteria and transformed into S bacteria. So live S bacteria were present again and they killed the mice.

Animals eat and digest food to obtain the energy available for life activities. Discuss energy use inanimals. In your discussion
marshall27 [118]

In addition to air and water, our body constantly needs regular inflow of food, which provides the energy reserves necessary for movement, breathing, thermoregulation, heart, blood circulation and brain activity. In the process of digestion of food decays to individual glucose molecules which then fall through the intestinal wall into the bloodstream. With blood flow glucose transported to the liver, where it is filtered and delayed in reserve. The pituitary gland supplies the pancreas and thyroid glands signal to the release of hormones that cause the liver to throw out the accumulated glucose in the bloodstream, and then delivers it to the blood to the organs and muscles that are in need of it. Having achieved the desired body glucose molecules penetrate into the cells, where it is converted into a source of energy that is available for use by cells. Thus, the process of continuous energy supply agencies depends on the level of glucose in the blood.
