Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
The carrier proteins in active transport act as a "pump" to carry/attach themselves to useful proteins for the cell. Called ATP
Transport proteins have the role of moving small molecules across the cell membrane. These proteins may assist substances in facilitated diffusion and active transport.
Nucleus to control translocation (transport of sucrose), via the production of enzymes and carrier proteins. Also, many mitochondria to produce ATP for active transport.
transport proteins play a role in both
ATP is hydrolyzed by transport proteins releasing energy. This energy is what is used to transport a molecule across a membrane and up its concentration gradient.
the carrier proteins that serve in facilitateddiffusiontransport
carrier molecule1. A molecule that plays a role in transporting electrons through the electron transport chain. Carrier molecules are usually proteins bound to a nonprotein group; they can undergo oxidation and reduction relatively easily, thus allowing electrons to flow through the system. There are four types of carrier: flavoproteins (e.g. FAD), cytochromes, iron-sulphur proteins (e.g. ferredoxin), and ubiquinone.2. A lipid-soluble molecule that can bind to lipid-insoluble molecules and transport them across membranes. Carrier molecules have specific sites that interact with the molecules they transport. Several different molecules may compete for transport by the same carrier. See transport protein.
Transport proteins in the cell membrane allow selective passage of small molecules from the external environment in to the cell.
The role of transport proteins in facilitated diffusion is to provide a hydrophilic route for the solute to cross the membrane.

i don't know ...look in the GOOGLE...NOW !!
Because the phosphlipid bilayer contains proteins, which are used to transport particles in and out of cells
ATP gives out energy.Energy is needed for active transportation.
The electron transport chain makes ATP. Each electron carrier alternates between being reduced and being oxidized.
active transport is kind of like diffusion, but unlike diffusion, it requires ATP(energy) and the molecule moves from low concentration to high concentration
Proteins have many uses such as: * Haemoglobin; has a transport role * Actin & Myosin; Make up muscle (contractile role) * Keratin & Collagen; Make up hair and skin (Structural role) * Antibodies and immunoglobulins; (immunological role) * Growth Hormone & Insulin; Regulatory role * Amylase, Catalase, protease; enzymes (Catalytic role) * Receptor Proteins; Communication role
Search Resultsdescribe how phospholipid molecules are oriented in the plasma membrane of acell. what role does a cellularmembrane play in passive transport? ... Active transport is important for cell function as, various activities keep taking place such as manufacture of protein, fat, etc.
ATP (adenosine triphosphate) is a molecule that provide energy to cells for active transport.
Functional proteins refer to a mixture of active proteins that form a complex mixture. The main role is to maintain and support the immune function in the body.
They provide the markers on the cell for recognition. Some also allow facilitated diffusion to occur.
In the field of passenger transport, 'active' transport refers to modes of transport which require the passenger to take a physical role in moving themselves. The most widely used modes of active transport are walking & cycling (running, swimming & even rowing are less common examples). Active transport is often recommended as part of a healthy lifestyle because it allows people to incorporate exercise into their daily routines (e.g. cycling to the shops or walking to work). In most cases, active transport is GOOD for you. However, it is sensible to assess the risks: for example, walking in a crime-spot at night or cycling too close to motorised traffic could be bad for you. [Note - in science, 'active transport' means something different]
They allow movement of salts and sugars through the plasma membrane
What role do chromosomes play when a cell makes proteins
The nucleus and ribosomes have a role in the creation of proteins.
FAD is a electron carrier that is reduced as glucose goes through oxidation. Then FAD becomes FADH2 and delivers it load of electrons the the systems in the electron transport chain.
