Transport proteins are needed when substances such as ions, nutrients, or molecules need to cross cell membranes, which are selectively permeable. These proteins facilitate the movement of substances that cannot easily diffuse through the lipid bilayer, either due to their size, charge, or polarity. Examples include glucose transporters and ion channels, which help maintain cellular homeostasis and enable essential cellular functions.

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.
Which kinds of proteins are needed for most cellular activities?

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.
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.
Are transparent proteins responsible for secreting proteins?
Transport proteins are not responsible for the secretion. Golgi vesicles transport proteins. Proteins synthesis occur in cytoplasm.
Packages proteins for transport out of the cell?
The Golgi apparatus is responsible for packaging and modifying proteins for transport out of the cell. It receives proteins from the endoplasmic reticulum, modifies them as needed, and then packages them into vesicles for transport to their final destinations.

Active transport always requires transport proteins during the process?
false
Is transport proteins a passive transport?
Carrier proteins can be involved in passive transport.
Move needed substances or waste materials through the plasma membrane?
transport proteins
What are the function of proteins in organism's?
Proteins have several functions in an organism. They are used to transport molecules and store molecules, they are used in movement, and they are needed for mechanical support.
Why are ATPases associated with active transport proteins?
ATPases provide the energy required for active transport by hydrolyzing ATP. These proteins pump ions or molecules against their concentration gradient, maintaining cellular homeostasis. The ATPase activity is essential for driving the conformational changes that allow active transport proteins to transport substances across the cell membrane.

Can proteins pass through transport proteins?
No the soluble proteins can not pass though the transporters on the membrane. Transport proteins are highly specific they only allow the transport of ions such as Na or K across the cell. But transport proteins such as Hemoglobin can carry oxygen or CO2 to all the tissues for respiration.
