Examples of active transport?
Active transport is the movement of ions or molecules across a cell membrane into a region of higher concentration, which requires energy and is assisted by enzymes. Examples of active transport are: the uptake of glucose in the intestines of people and the uptake of mineral ions into the root hairs of plants.
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.
How does a cell solve the problem of glucose being to big to pass through the cell membrane?
Cells use transport proteins, such as glucose transporters, to facilitate the movement of glucose molecules across the cell membrane. These transporters act as channels or carriers that allow glucose to pass through the membrane, overcoming the barrier posed by its size.
What requires energy ATP to transport molecules against a concentration gradient?
The process that requires energy in the form of ATP to transport molecules against a concentration gradient is known as active transport. This mechanism allows cells to move substances from an area of lower concentration to an area of higher concentration, which is essential for maintaining cellular homeostasis. Examples include the sodium-potassium pump, which regulates ion concentrations, and the uptake of glucose in intestinal cells. Active transport is crucial for various cellular functions, including nutrient absorption and waste removal.
What is the Carrier of glucose in the human bodies?
The primary carrier of glucose in the human body is insulin, a hormone produced by the pancreas. Insulin facilitates the uptake of glucose from the bloodstream into cells, particularly in muscle and adipose (fat) tissues, where it is used for energy or stored as glycogen. Additionally, glucose transport proteins, such as GLUT1 and GLUT4, help transport glucose across cell membranes.
What Carrier Proteins Transport Glucose Into A Muscle Cell?
Glucose transport into muscle cells is primarily facilitated by the glucose transporter 4 (GLUT4) carrier protein. This transporter is insulin-responsive and plays a crucial role in regulating glucose uptake by muscle cells to meet energy demands during exercise and recovery.

Examples of active transport are: the uptake of glucose in the intestines of people and the uptake of mineral ions into the root hairs of plants.
What are some Real life examples of active transport?
Engulfing, protein transfer, and ill get back to y'all on the last one lol ^^^ Those aren't really examples of active transport, just names of characteristics of an active transport. Active transport is the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy. Endocytosis-A process in which a cell takes in materials from the outside by engulfing and fusing them with its plasma membrane. There are two types of endocytosis, called phagocytosis, which means cell-eating, and pinocytosis, which means cell-drinking. Sodium-Potassium Pump-Nerve cell membranes also contain carrier proteins that actively transport sodium ions out of the cell and potassiu ions into the cell.
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.
How does active transport facilitate the movement of glucose into muscle cells?
Active transport is a process that requires energy to move molecules across a cell membrane. In the case of glucose entering muscle cells, active transport proteins use energy to pump glucose molecules against their concentration gradient, allowing them to enter the cell even when there is a higher concentration of glucose outside the cell. This process ensures that muscle cells have a constant supply of glucose for energy production and muscle function.
Examples of active transport in animals?
Active transport in animals can include the movement of ions like sodium and potassium across cell membranes using ATP-powered pumps. Another example is the uptake of glucose by epithelial cells in the intestines and kidneys against a concentration gradient. In muscle cells, calcium ions are actively transported into the sarcoplasmic reticulum after muscle contraction.
Why respiration rates increase in root hair cells during the uptake of mineral ions?
due to active transport system
What is the relationship between GLUT4, insulin, and glucose in the context of cellular glucose uptake?
GLUT4 is a protein that helps transport glucose into cells. Insulin signals cells to increase the production of GLUT4, allowing more glucose to enter the cell. This process is crucial for regulating blood sugar levels and providing cells with energy.
What is the relationship between GLUT4, insulin, and glucose in the process of cellular glucose uptake?
GLUT4 is a protein that helps transport glucose into cells. Insulin signals the body to increase the production of GLUT4, allowing more glucose to enter cells. This process is essential for regulating blood sugar levels and providing cells with energy.
Cells take in oxygen by simple diffusion and glucose by facilitated diffusion Therefore oxygen uptake and glucose uptake will differ from each other in all respects except what?
Oxygen uptake and glucose uptake will differ in terms of the transport mechanisms involved, as oxygen is taken in by simple diffusion while glucose requires facilitated diffusion. Other factors such as energy requirements, concentration gradients, and specific transport proteins involved may also vary between the two processes.
Which pancreatic hormone stimulates the uptake of glucose by cells?
The hormone that predominately signals glucose uptake by the cells is the insulin. It is secreted in the pancreas by the islets of Langerhans.
Which cell type in the pancreas is responsible for the uptake of glucose in cells?
Beta Islet Cells
