Is a protein channel active transport?
They are two major active transport proteins.
What is the difference between countertransport and antiport?
Cotransport is the name of a process in which two substances are simultaneously transported across a membrane by one protein, or protein complex which does not have ATPase activity. Different types of co-transport Symport When both substances are transported in the same direction the transport protein is known as a symport . Antiport When the substances are transported in opposite directions the transport protein is known as an antiport.
Are osmosis and endocytosis passive transports?
It is an active transport,Transport mechanisms fall into two catagories passive and active. Passive transport mechanisms do not require the cell to do work for the substance to enter or leave the cell. Instead the energy involved comes from the kinetic energy of the molecules in solution. Active transport mechanisms involve the cell to use cellular energy usually in the form of ATP to power special protein pumps to bring material into the cell.Passive transport mechanisms Active Transport mechanismsSimple diffusionOsmosisFacilitated DiffusionSimple protein channelsGated channelsActive transport via protein pumpsBulk flow mechanismsendocytosisphagocytosispinocytosisexocytosisThe passive transport mechanisms and the protein pump mechanisms involve movement of substances as single molecules across the membrane. The "bulk" flow mechanisms endocytosis and exocytosis enable the cell to take in very large packages of molecules...say a food item from the environment. Many books treat these bulk flow mechanisms as separate from active transport for that reason.
What are two types of cellular transport that do not require energy?
Passive transport never requires energy - hence the name passive. Active transport requires the input of energy. Two types of active transport are; primary (using pumps) and secondary (using anti or symports).
What process involves the use of specific carrier molecules?
two processes requiring the use of protein carrier molecules?
Is a protein channel active transport?
They are two major active transport proteins.
Describe the two methods of active transport?
The 2 methods of active transport are taking the energy and using the energy to where the cell is doing the work,the cell will transport what is needed and all us done.
Identify 2 methods of Active transport?
The two principle methods of active transport are ATP-driven active transport (e.g. Na+ - K+ ATPase) and ion gradient-driven active transport, as in the Na+ - glucose symport.
What types of transport require ATP?
The two types of cell trnsport it Passive Transport and Active Transport. Active Transport does require energy to move into and out of the cell. Passive Transport doesn't require energy to move into and out of the cell. Hope I helped!
What are the two types of transport across the cell membrane?
active transport and passive transport. active transport requires energy and able to transport molecules from low concentration side to higher concentration side. passive is just like a tube that connects innner side and outer side. it requires no energy but unable to do like active transport does
What is a description of the process of cotransport?
In cotransport, a membrane protein couples the transport of two solutes.
What type of transport does not require energy?
passive transport does not need energy. And two types of passive tansport are osmosis and diffusion
What methods can be used to study protein-protein interactions?
There are numerous methods for protein protein interactions. Biochemical methods include: 1) Coimmunoprecipitation - proteins are isolated with specific antobody. 2) Affinity Electrophoresis- estimates protein binding. 3) cross linking - to fix protein interactions before isolating 4) Quantitative immunoprecipitation: to detect interactions between endogenous non tagged proteins. Molecular Biology methods: 1) protein probing 2) two hybid system 3) phage display Genetic methods: 1) Isolation of extragenetic suppressors ,Synthetic mutants

What are the two components of hemoglobin?
lol it is hobgoblin I believe it is iron
