3. All of the organic molecules are based on which element?

Ulleksa [173]

Answer:

<h2>Carbon. </h2>

Explanation:

Life is based on carbon; organic chemistry studies compounds in which carbon is a central element. The properties of carbon make it the backbone of the organic molecules which form living matter. Carbon is a such a versatile element because it can form four covalent bonds.

During the cross-bridge cycle in muscle cells, myosin motors hydrolyze ATP as fuel to create a pulling force on actin fibers. Pl

exis [7]

Answer and Explanation:

In rest, attraction strengths between myosin and actin filaments are inhibited by the tropomyosin. When the muscle fiber membrane depolarizes, the action potential caused by this depolarization enters the t-tubules depolarizing the inner portion of the muscle fiber. This activates calcium channels in the T tubules membrane and releases calcium into the sarcolemma. At this point, tropomyosin is obstructing binding sites for myosin on the thin filament. When calcium binds to the troponin C, the troponin T alters the tropomyosin by moving it and then unblocks the binding sites. Myosin heads bind to the uncovered actin-binding sites forming cross-bridges, and while doing it ATP is transformed into ADP and inorganic phosphate which is released. Myofilaments slide impulsed by chemical energy collected in myosin heads, producing a power stroke. The power stroke initiates when the myosin cross-bridge binds to actin. As they slide, ADP molecules are released. A new ATP links to myosin heads and breaks the bindings to the actin filament. Then ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, which starts a new binding cycle to actin. Z-bands are then pulled toward each other, thus shortening the sarcomere and the I-band, and producing muscle fiber contraction.

When a potassium ion (K) moves from the soil into the vacuole of a cell on the surface of a root, it must pass through several c

Sindrei [870]

Answer:

C) primary cell wall --> plasma membrane --> cytoplasm --> tonoplast

Explanation:

When a potassium ion moves from the ground into a vacuole of a plant cell, it must pass through the different structures that are part of it.

First, the outermost layer of the cell is the cell wall. Plant cells may have a primary and a secondary wall, but the latter is not always present. The primary wall is always located outwards (and in the case of having a secondary wall, it will be located between the primary wall and the plasma membrane).

Then, inside the cell wall, we will find the plasma membrane (also called plasmalemma).

When crossing the membrane, the ion will be in the cytoplasm of the cell and will be directed towards the vacuole, which is surrounded by its membrane called tonoplast. The vacuole is an organelle that has no definite shape, although it is always surrounded by the tonoplast, and it contains different substances such as water and enzymes.
