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.

What three major processes of nutrient absorption must be combined with a carrier molecule for transport?
The three major processes of nutrient absorption requiring a carrier molecule for transport are facilitated diffusion, active transport, and cotransport (symport). These processes are essential for the absorption of nutrients such as glucose, amino acids, and ions in the small intestine. The carrier molecules help transport these nutrients across the cell membrane.
Why do solutes move across a lipid bilayer?
Solutes can move across a lipid bilayer through passive diffusion, facilitated diffusion, or active transport. Passive diffusion occurs when solutes move down their concentration gradient, facilitated diffusion involves the use of transport proteins, and active transport requires energy to move solutes against their concentration gradient.
Why absorption rate of galactose is more than glucose?
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.
Intestinal cells absorb glucose via active transport so would the glucose absorption decrease if all the mitochondria within these intestinal cells were destroyed?
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.
Amino acids absorbed through two processes of?
Amino acids are absorbed through two processes: active transport and facilitated diffusion. Active transport requires energy and is used for absorption of essential amino acids, while facilitated diffusion does not require energy and is used for absorption of non-essential amino acids. Both processes occur in the small intestine.
Is monosaccharide absorption active or passive?
active transport -taking anatomy and physiology II
Absorption mechanism that requires energy?
Active transport
Can polar molecules cross the lipid bilayer?
Yes, polar molecules can cross the lipid bilayer through facilitated diffusion or active transport mechanisms.
When nutrients move from the digestive system and to the bloodstream?
That's called the process of absorption. The biological processes that allow absorption are diffusion and osmosis.
Why cant large materials move across the membrane by facilitated diffusion or active transport?
because of lipid insolubility
What is the process that requires the use of energy to move materials across a membrane?
Active transport is the process that requires the use of energy to move materials across a membrane. This process involves the movement of molecules against their concentration gradient, requiring energy input from the cell.

Why is urea absorption an active process?
Urea absorption is considered an active process because it requires energy to move urea against its concentration gradient. This is facilitated by transport proteins in the cell membranes of the renal tubules, which utilize ATP to actively transport urea from areas of lower concentration to areas of higher concentration. This active transport mechanism is crucial for maintaining proper nitrogen balance and facilitating the reabsorption of water in the kidneys.
