Which term refers to the collections of electron carriers that are embedded in the inner mitochondrial membrane and in the thylakoid membrane?
The term that refers to the collections of electron carriers in the inner mitochondrial membrane and thylakoid membrane is the electron transport chain. This chain plays a crucial role in generating ATP through oxidative phosphorylation in the mitochondria and in photosynthesis in the chloroplasts.
Which term refers to the movement of materials through cell membrane without using the cells energy?
active transport
Which term refers to the moventment of materials through a cell membrane without using the cells energy?
passive transport
Which term refers the movement of materials through a cell membrane without using the cell's energy?
active transport
In which membrane is the electron transport chain located?
The outer membrane is where the electron transport chain is located.
Which type of transport requires assistance from membrane proteins?
Active transport requires assistance from membrane proteins. These proteins, such as ion pumps and carrier proteins, help move molecules against their concentration gradient, requiring energy input to drive the process.
What are the two membranes that surround and define the nucleus?
The two membranes that surround and define the nucleus are the inner nuclear membrane and the outer nuclear membrane. These membranes are responsible for separating the nucleus from the rest of the cell and regulating transport in and out of the nucleus through nuclear pores.
Which term refers to movement of materials through a cell membrane without using the cell's energy?
passive transportPassive transport is the term. Active transport is moving of materials WITH energy.Passive transportpassive transportdiffusionDiffusion, but if it's water then it's called osmosis. They're the same basic thing though.diffusion
Structure regulates the transport in and out of the cell?
The cell membrane is the structure that regulates the transport of molecules in and out of the cell. It is selectively permeable, allowing certain substances to pass through while restricting others. Transport proteins embedded in the membrane help facilitate the movement of specific molecules across the membrane.
What is the structure of transport?
membrane phospolipids
What is selective transport?
Selective transport refers to the movement of specific substances across a membrane, such as a cell membrane or an organelle membrane, through specialized transport proteins or channels. This process allows cells to regulate the passage of certain molecules in and out of the cell, maintaining internal homeostasis. Selective transport ensures that only certain molecules are allowed to cross the membrane, while others are excluded.
Why must transport proteins be peripheral proteins?
Transport proteins must be peripheral proteins because they need to be able to move within the cell membrane to facilitate the transport of molecules across the membrane. Peripheral proteins are not embedded within the lipid bilayer of the membrane, allowing them to move more freely and interact with molecules on both sides of the membrane. This mobility is essential for transport proteins to effectively transport molecules across the cell membrane.
