Answer:
Antioxidants help cells perform their functions against something called free radicals. Free radicals are molecules that happen to be produced when your body breaks down food and/or when you inhale or are exposed to tobacco products. These molecules play a role in leading to diseases such as; Heart disease and cancer. When plants synthesize, they collect many non-enzymatic Antioxidants like ascorbic acid and phenolic. Since plants have many more sites of ROS generation, Therefore, they could evolve more efficient non-enzymatic Antioxidant systems than humans because of their high intake and exposure to oxygen. (answer yourself about the structure in your own words using the information I gave you). Diet relates to both the function, structure and health of your cells. Having a balanced diet helps your cells to happily work and produce energy for your daily use. A balanced diet supplies your body with nutrients so it can work effectively. Without balanced nutrition, your body is way more prone to disease, fatigue, low performance and infections.
I hope this helped you!
In what organisms are you referring to?
Answer:The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.
Explanation:
Answer:
It means that the cell membrane allows certain substances to pass through and not others. As the cell membrane consists of a phospholipid bilayer with a hydrophobic core, only small uncharged hydrophobic molecules can pass through the cell membrane e.g. glucocorticoid and other larger charged particles require transporters or channel proteins to pass through the cell membrane, e.g. glucose.
