What are three factors that affect the health of cell membranes and how do they do it?

Answer 1

Many highly reactive molecules can affect the cell membranes negatively by modifying the chemical structure of the double layer of lipids that constitute most of these membranes. The most reactive of these molecules are strong oxidants, which can damage other molecules and the cell structures of which they are a part. Phosphorous is an essential nutrient, as it assists and strengthens energy metabolism, DNA structure, and cell membranes. Zinc is both an antioxidant enzyme co-factor and a stabilizer of cell membranes. It is not an oxidant so it will not damage the molecules or cell structures as mentioned above.

Answer 2

1. Temperature: Extreme temperatures can disrupt the fluidity of cell membranes, affecting their permeability and function.
2. pH levels: Changes in pH can alter the structure of cell membranes and affect the activity of membrane-bound proteins.
3. Lipid composition: The types and ratios of lipids in cell membranes influence their fluidity and stability, impacting various cellular processes.

Answer 3

A cell membrane refers to the semipermeable membrane that surrounds the cytoplasm of a cell. Three factors that affect its health are diseases, obesity and hormonal imbalances.

Answer 4

Diffusion, osmosis, and facilitated diffusion.
