No, lipid absorption is primarily a passive process. It occurs through simple diffusion in the small intestine, where lipids are broken down into smaller molecules and then absorbed into the bloodstream. Some specialized transport proteins may facilitate the absorption of certain lipids, but it is not considered active transport.
Yes, glucose absorption would likely decrease if all the mitochondria within the intestinal cells were destroyed. Mitochondria are essential for generating the energy (ATP) needed for active transport processes. Without mitochondria, the cells would lack the energy required for effective glucose absorption through active transport.
The absorption rate of galactose is higher than glucose because galactose is transported into enterocytes by a secondary active transport mechanism that involves a carrier protein, which allows for faster absorption. In contrast, glucose is primarily absorbed through facilitated diffusion, which is a slower process.
absorption of nutrients, because microvilli increase the surface area available for absorption. These cells are commonly found in the small intestine to facilitate the absorption of essential nutrients from digested food.
Epithelial cells primarily function to form protective barriers and facilitate absorption of nutrients rather than directly absorb water. However, in certain tissues, like the intestinal epithelium, water absorption occurs alongside the absorption of nutrients through osmosis and active transport mechanisms. Additionally, in the kidney's collecting ducts, epithelial cells regulate water reabsorption under the influence of hormones like antidiuretic hormone (ADH). Thus, while epithelial cells can be involved in water absorption, it depends on their specific location and function within the body.
ATP is needed for these two transport mechanisms to occur.

They develop a cytoplasmic hair-like elongation which increases its surface area for more absorption. It also has a large number of mitochondria which provides energy needed for the active uptake of minerals.
Active transport
That's called the process of absorption. The biological processes that allow absorption are diffusion and osmosis.
