Is Receptor-Mediated Endocytosis Passive or Active Transport?
It is niether. Its is passive actually. http://www.mansfield.ohio-state.edu/~sabedon/campbl08.htm #38. under Endocytosis, which is active passport, includes the example of Receptor-Mediated Endocytosis.
When the sarcomere is at rest what is covering the active sites on actin?
When the sarcomere is at rest, the active sites on actin are covered by tropomyosin molecules. Tropomyosin blocks the myosin-binding sites on actin, preventing cross-bridge formation and muscle contraction.
What is the time in which cross bridges are active called?
The time in which cross bridges are active during muscle contraction is called the "cross-bridge cycle." This cycle involves the binding of myosin heads to actin filaments, power stroke generation, and detachment of the cross bridges.
Does active transport move molecules against the concentration gradient?
Yes, active transport moves molecules against the concentration gradient.
How do microvilli and mitrochondria help in the active transport?
Microvilli increase the surface area of the cell membrane, allowing for more transport proteins to be present to facilitate active transport of molecules against their concentration gradient. Mitochondria provide the energy in the form of ATP needed to power the active transport process.
What type of plate boundary triggers the formation of active volcanoes as magma rises beneath the surface?
Oceanic-to-Oceanic plate boundary triggers the formation of active volcanoes as magma rises beneath the surface.Transform plate boundaries trigger the formation of active volcanoes as magma rises beneath the surface.
Antibacterial drugs that inhibits cell wall synthesis?
Penicillin destroys cell walls of bacteria by interfering with the formation of Peptide cross-bridges of peptidoglycan to prevent the formation of an active cell wall.
What unlocks the active site of an actin molecule?
The binding of ATP to actin causes a conformational change that exposes the active site for myosin binding. This allows for the formation of cross-bridges between actin and myosin during muscle contraction.
An enzyme is a protein with a pocket on its surface called an?
An enzyme is a protein with a pocket on its surface called an active site. This is where the binding of substrate molecules take place and where chemical reaction happens.

How can surface tension reduction be achieved in a liquid system?
Surface tension reduction in a liquid system can be achieved by adding surfactants or surface-active agents. These substances disrupt the intermolecular forces at the liquid's surface, reducing the cohesive forces between molecules and lowering the surface tension.
An active site is a pocket lke structure in the surface of an enzyme where substrate molecules attach thus enabling a chemical reaction to take place?
true

What is moved by active transport?
Molecules are moved by active transport.

The time in which cross bridges are active during muscle contraction is called the "cross-bridge cycle." This cycle involves the binding of myosin heads to actin filaments, power stroke generation, and detachment of the cross bridges.
Does active transport move molecules against the concentration gradient?
Yes, active transport moves molecules against the concentration gradient.
How does an active volcano effect earths surface?
an active volcano affects the surface because of where the place is located
