What else can I help you with?
Is a cell membrane is a brain?
No, a cell membrane is not a brain. The cell membrane is a semipermeable barrier that surrounds the cell and controls what substances can enter and leave the cell. The brain is a complex organ responsible for processing thoughts, emotions, and controlling movement in the body.
What are 2 examples of substances that contain complex molcecules?
Two examples of substances that contain complex molecules are DNA and proteins. DNA is a complex molecule found in the nucleus of cells that carries genetic information, while proteins are composed of long chains of amino acids and play a variety of essential roles in the body.
What allows certain substances to pass into and out of the nucleus of the cell?
Nuclear membrane
What are the membrane-bound sacs the Golgi complex complex packs proteins and other materials into?
Vesicles
Which organelle carries substances to other part of a cell?
Golgi complex
What kind of particle ion molecule or molecular complex diffuses through a cellulose membrane?
i am not sure
Does a complex carborhydrate have a phosphate group attached to the sugar molecule?
Complex carbohydrates can be attached to a phosphate group to form glycoproteins. A glycoprotein is a sugar molecule that are attached to a cell membrane.
The typical prokaryotic flagellum features what?
The typical prokaryotic flagellum features a long, helical filament made of flagellin proteins that allows for movement. It is anchored to the cell membrane and driven by a motor complex that rotates to propel the cell forward.
Can ATP synthase move about in the cytosol of the mitochondrian?
Definitely not, as ATP synthase is a membrane-bound enzyme. It is integrated into the inner mitochondrial membrane (and the thylakoid membrane in chloroplasts).
Is a cell membrane is a brain?
No, a cell membrane is not a brain. The cell membrane is a semipermeable barrier that surrounds the cell and controls what substances can enter and leave the cell. The brain is a complex organ responsible for processing thoughts, emotions, and controlling movement in the body.
Why are the components of the electron transport chain embedded in the inner mitochondrial membrane rather than floating freely in the cytoplasm of mitochondrial matrix?
The components of the electron transport chain are embedded in the inner mitochondrial membrane to facilitate the efficient transfer of electrons and the generation of a proton gradient, which is necessary for ATP production. Being embedded in the membrane allows for the organization of the components in a specific sequence to create a functional chain. It also helps to prevent the loss of protons and electrons to ensure the proper functioning of the electron transport chain.
How do cells move large molecules into and out of the cell?
Cells use a variety of methods to move large molecules in and out of the cell. Endocytosis involves the cell engulfing large molecules by forming vesicles from the cell membrane. Exocytosis is the reverse process, where vesicles containing large molecules fuse with the cell membrane to release their contents outside of the cell. Transport proteins embedded in the cell membrane can also facilitate the movement of large molecules across the membrane through processes like facilitated diffusion and active transport.
What are electrons passed from during electron transport chain?
Electrons are passed from one protein complex to another in the electron transport chain, which is a series of protein complexes embedded in the inner mitochondrial membrane. This process generates a proton gradient that drives the production of ATP, the cell's energy currency.
Where do the reactions of each electron transport chain occur?
In the inner membrane of the mitochondria.
Is DNA a complex molocule?
Yes, it is a very complex molecule.
Why cant water dissolve compounds such as oil?
Water is a polar molecule, while oil is a nonpolar molecule. Polar molecules like water are only able to dissolve other polar or ionic substances, not nonpolar substances like oil. This is due to the differences in their electrostatic interactions, preventing water from effectively breaking down and dissolving oil molecules.
What are 2 examples of substances that contain complex molcecules?
Two examples of substances that contain complex molecules are DNA and proteins. DNA is a complex molecule found in the nucleus of cells that carries genetic information, while proteins are composed of long chains of amino acids and play a variety of essential roles in the body.
