Answer:
All the parts of the cell involved in getting oxygen into your cells so it can help release energy are Mitochondria , Ribosomes ,Peroxisomes and Vesicles.
Explanation: Explaination of all four parts of the cell involved in getting oxygen into our cells so it can help release energy-
- <u>MITOCHONDRIA</u> -:"Mitochondria (singular = mitochondrion) are also referred to as a cell's" powerhouses "or" energy factories "because they are responsible for producing the main energy-carrying molecule of the cell, adenosine triphosphate ( ATP). ATP reflects the cell's short-term stored energy. The method of producing ATP using the chemical energy found in glucose and other nutrients is cellular respiration. This method utilizes oxygen in mitochondria and creates carbon dioxide as a waste product.
- <u>RIBOSOMES -: </u>The cellular structures responsible for protein synthesis are ribosomes. Ribosomes appear either as clusters (polyribosomes) or single, tiny dots floating freely in the cytoplasm when viewed through an electron microscope. They can be connected to the plasma membrane's cytoplasmic side, or to the endoplasmic reticulum's cytoplasmic side and the nuclear envelope's outer membrane.
- <u>PEROXISOMES -:</u>Peroxisomes are specialized for the use of molecular oxygen to conduct oxidative reactions. They produce hydrogen peroxide, which they use for oxidative purposes, by means of the catalase they contain, removing the excess.
- <u>VESICLES -:</u> A byproduct of the transformation of vesicles is oxygen. Also, Prochlorococcus develops a large number of vesicles that are used for many important functions: virus protection, genetic information transfer, and nutrient transmission. Via a number of pathways, all cells generate vesicles.
Hence , the parts of the cell involved in getting oxygen into our cells so it can release energy are <u>mitochondria (the main part), ribosomes ,peroxisomes and vesicles.</u>
Yes, because even though other trees produce more oxygen, the small trees will still produce some oxygen. On top of this there are more small trees than big trees, so even though they make less oxygen, in whole they end up making more when added together!
