Question

How is ATP used to produce movement in a cell?

Answer 1

this one?

Answer 2

yes! thank you so much!

Answer 3

hmm...let me look for a sec

Answer 4

take all the time you need!

Answer 5

hydrolysis ?

see below

"Energy transfer is a process that occurs in all cellular activities. Cellular movement is a function towards muscle contraction, cytoplasmic streaming, and locomotion. Muscle contraction is embodied with sliding filaments.

---> It is also composed of contractile proteins such as thick filament, thin filament, sarcomere, myofibril, and myofiber that use ATP hydrolysis to contract.

Cytoplasmic streaming is the movement of the living substance (cytoplasm) within a plant or animal cell. The motion transports nutrients, enzymes, and, in plants, large virus particles within the cells. Locomotion incorporates cilia, flagella, and pseudopodia into creatures. These are means of locomotion powered by ATP hydrolysis for some unicellular organisms with 9 + 2 microtubules such as protists, archeozoans, and bacteria. The activities in cell membrane components are synthesized in the endoplasmic reticulum (ER), transported as vesicles to the Golgi apparatus where they are modified, and then are transported to the cell surface where they deliver their contents to the cells exterior and become a part of the cell membrane in a process called exocytosis. The reverse of this process, bringing nutrient containing particles from out side to the inside of the cell is called endocytosis.

---> In addition, in the cell, dynein binds to the microtubule and uses the energy in ATP molecules to power their motor molecules to move from the positive end of the microtubule toward the negative end of the microtubule.

--->Each small step, requires the hydrolysis of one ATP molecule. Dynein pulls subcellular materials toward the center of the cell. A closely related protein, kinesin, also pulls subcellular materials in the opposite direction. In general, ATP is used for all energy transfer processes in cellular activities."

Answer 6

is that wrong? lol

Answer 7

thank you sooooo much! this is the exact information i needed! thank you again!
