Answer:
The respiration process is carried out by our cells.
Explanation:
Respiration, is one of the characteristics of living organisms. It is the process whereby organisms acquire energy needed for their life processes. Respiration breaks down the food molecules we ingest and release the energy stored in their bonds.
When we eat, digestion occurs and breaks down our food into glucose, which then enters the cell to be broken down via series of metabolic reactions. In eukaryotic cells, the synthesis of ATP occurs in the mitochondrion organnelle.
Hence, the phrase we respire because our cells respire means its in our cells that the process of respiration take place.
Answer:
D. It uses no electricity
Explanation:
As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen; when the weightlifter’s muscle cells are not able to take in enough oxygen to make very much ATP, as he competes in the event.
Explanation:
Anaerobic respiration takes place when there is too low or no oxygen to perform aerobic respiration. This transfers the energy to the cells from glucose. It produces energy very quickly along with lactic acid and other waste products.
Anaerobic respiration is highly useful when short bursts of energy are required very quickly to energize the muscles to perform high intensity activities like wrestling, weightlifting, intense short workouts, etc.
Lactic acid fermentation causes the muscles to burn out when high intense short burst physical activities are performed.
DNA is a double stranded nucleic acid which forms a double-helix structure made up of two chains of nucleotides, quite similar to that of a twisty ladder. RNA is only made up of a single strand of amino acids and therefore only forms a single stranded helix structure.
