Which absorptive process in the small intestine requires a carrier and energy to transport nutrients into absorptive cells?
Active transport in the small intestine requires a carrier protein and energy (in the form of ATP) to move nutrients against their concentration gradient into absorptive cells. This process allows the absorption of nutrients like glucose and amino acids that are present at lower concentrations in the intestines compared to inside the absorptive cells.

What type of transportation requires energy to move a molecule?
Active transport requires energy to move molecules across a cell membrane, typically against a concentration gradient. This process is vital for maintaining proper internal conditions within a cell. Examples of active transport mechanisms include pumps and vesicular transport.
Is facilitated diffusion an example of active transport?
No, facilitated diffusion is a type of passive transport where molecules move across a cell membrane with the help of transport proteins. Active transport, on the other hand, requires energy to move molecules against their concentration gradient.
Sound does not travel through a vacuum?
No. Sound is transmitted as vibrations, that pass from one group of atoms to the next, thus, it requires the presence of atoms that transport the sound wave.No. Sound is transmitted as vibrations, that pass from one group of atoms to the next, thus, it requires the presence of atoms that transport the sound wave.No. Sound is transmitted as vibrations, that pass from one group of atoms to the next, thus, it requires the presence of atoms that transport the sound wave.No. Sound is transmitted as vibrations, that pass from one group of atoms to the next, thus, it requires the presence of atoms that transport the sound wave.
Why active transport requires energy?
Active transport requires energy because it moves molecules or ions against their concentration gradient, from areas of lower concentration to areas of higher concentration. This process goes against the natural tendency of molecules to diffuse down their concentration gradient, requiring the input of energy in the form of ATP to drive the transport proteins involved.
How can active transport differ from passive transport?
Active transport requires energy input to move molecules against their concentration gradient, while passive transport does not require energy and moves molecules along their concentration gradient. Active transport usually involves the use of transport proteins, such as pumps or carriers, while passive transport relies on diffusion or facilitated diffusion.
What is it called When a nutrient moves from an area of higher concentration into an absorptive cell where the concentration is lower?
This process is called active transport. It requires energy to move nutrients against their concentration gradient into the absorptive cell.
Why does the small intestine have a blood supply?
The small intestine requires a rich blood supply to deliver nutrients absorbed from food to the rest of the body. The blood vessels in the small intestine also help remove waste and transport it to the liver for processing. This intricate network of blood vessels supports the high metabolic activity of the small intestine.
Why is Mitochondria compared to the small intestine?
The mitochondria in every cell are like a cells digestive system because they take nutrients from their surroundings and create energy about of them. People could not like without a digestive system and mitchondria. The energy that all animals need to survive is called ATP.
Small intestine in herbivores and carnivores?
In herbivores, the small intestine is longer and more complex to aid in the digestion of plant material, which requires more time and surface area for absorption of nutrients. In contrast, carnivores have a shorter and simpler small intestine because the digestion of meat is more straightforward and requires less time and surface area for absorption of nutrients.
Why are glucose and galactose absorbed by active transport?
Glucose and galactose are absorbed by active transport in the small intestine because they are structurally similar and compete for the same carrier protein, known as SGLT1. This carrier protein requires energy to bring glucose and galactose molecules into the intestinal cells against their concentration gradient. This process ensures efficient absorption of these important nutrients.
What energy is required to move nutrients across a cell membrane?
active transport requires energy to move stuff and the energy is ATP
How do nutrients get into cells and what is the process involved in their transportation?
Nutrients enter cells through a process called active transport or passive diffusion. Active transport requires energy and specific carrier proteins to move nutrients across the cell membrane, while passive diffusion relies on the concentration gradient to allow nutrients to move freely into the cell. Once inside the cell, nutrients are transported to different parts of the cell through various pathways, such as vesicle transport or protein channels.
Where does active transport occur i plants?
Active transport in plants occurs mainly in the root cells, where the uptake of essential nutrients from the soil takes place. This process requires energy to move molecules against their concentration gradient, ensuring that plants can absorb the necessary nutrients for growth and development.
Why does the digestif system have more organs?
The digestive system has more organs because it is responsible for breaking down food, extracting nutrients, and eliminating waste from the body. Each organ performs specific roles such as digestion (mouth, stomach, small intestine) and absorption of nutrients (small intestine), which requires a complex network of organs working together.
What types of transport requires no energy?
Passive Transport
What type of transport requires energy to move molecule?
Active transport requires energy to move a molecule.
What does not describe passive transport?
Active transport requires energy.
