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.
Ions are atoms which have a missing electron or an extra one. This is what gives the ion its positive or negative electrical charge. Isotopes are atoms which contain a different number of neutrons.
To clean/protect themselves which results in that
Answer:
The correct answer is biological.
Explanation:
When any pathogen invades the body, it has to pass several lines of defence. The first barrier is the skin and mucous membrane which is a physical and chemical barrier. The second line of defence is the non-specific response by macrophages, neutrophils and interferon. After crossing these two barriers the third line of defence comes into action in which, the B- cells and T-cells act specifically on the pathogen and destroy it.
