What else can I help you with?
Mitochondria are needed for the cell to transport glucose across the cell membrane into the blood what is the method that the cell uses to do this?
Mitochondria are not directly involved in transporting glucose across the cell membrane. Glucose transport into the cell is primarily facilitated by glucose transport proteins located on the cell membrane. These transport proteins utilize concentration gradients to move glucose into or out of the cell as needed.
Why do cells need carriers proteins that transport glucose?
Large molecules, such as glucose, are not able to pass through the cell membrane. Therefore proteins are needed to transport them across.
What type of transport does a small molecule enter a cell with help from a membrane protein additional energy is needed to complete this process?
Facilitated
What substances used to help active transport occur within cells?
Proteins are major substances involved in active transport within cells. Examples include ion pumps like Na+/K+ ATPase and transporters like glucose transporters. ATP provides the energy needed for these proteins to actively transport molecules across the cell membrane.
What are glucose carriers?
Glucose carriers are specialized proteins located in cell membranes that facilitate the transport of glucose into cells. They function by binding to glucose molecules and undergoing conformational changes to shuttle glucose across the membrane, a process that can be either passive or active depending on the carrier type. Key glucose carriers include GLUT transporters, which operate primarily through facilitated diffusion, and SGLT transporters, which utilize sodium gradients to actively transport glucose. These carriers are essential for maintaining glucose homeostasis in the body, enabling cells to access the energy needed for various metabolic processes.

What Transport mechanism is used to remove glucose filtrate the enery needed for that purpose?
Active Transport

Facilitated
How is passive transport different then active transport?
Passive transport does not require energy input and relies on the concentration gradient to move molecules across the cell membrane. Active transport requires energy (usually in the form of ATP) to move molecules against the concentration gradient.

How does nutrients cross plasma membrane?
Things like oxygen, CO2 and lipids cross the membrane with simple diffusion. Water can cross the membrane with osmosis when the water moves through a channel protein in the plasma membrane. Glucose, potassium, sodium etc. moves through a carrier protein in the membrane with the process of active movement. In the process of active movement energy is needed and it is given by the glucose or ATP from the cell.
Move needed substances or waste materials through the plasma membrane?
transport proteins
Large numbers of which organelle would be present in a cell that actively transports a lot of glucose across its membrane?
Active transport requires energy. Energy is released as a result of respiration, and respiration takes place in mitochondria. So major sites of active transport, such as kidney nephrons and villi in the small intestine need relatively large number of these organelles.
What are the materials needed in cellular respiration?
The materials needed in cellular respiration are glucose and oxygen. Glucose is the source of energy, and oxygen is the final electron acceptor in the electron transport chain, which drives the production of ATP in the mitochondria.
What is the function of a thykaloid membrane?
The thylakoid membrane is where the light-dependent reactions of photosynthesis take place in plant cells. This membrane contains chlorophyll and other pigments that capture light energy and convert it into chemical energy in the form of ATP and NADPH. It also houses the protein complexes involved in the electron transport chain, which generates the energy needed to produce glucose during photosynthesis.
