Carbohydrate is a group of compounds that is comprised of very simple units of sugar called the monosaccharide. From the prefix "mono", this means that the simplest unit is composed only of one block of sugar. Monosaccharide examples include: glucose, galactose, and fructose. From the given lists above, the one that does not match perfectly is the fourth pair. Glycogen is a multibranched polysaccharide.
ANSWER: glycogen - monosaccharide
Answer: The calcium ion binds to troponin, and this slides the tropomyosin rods away from the binding sites.
Explanation:
Contraction and relaxation of muscle cells brings about movements of the body. The contractile myofilament called sarcomeres are bounded at each end by a dense stripe called the Z - line, to which the myosin fibres are attached, and lying in the middle of the sarcomere are the actin filaments, overlapping with the myosin.
When action potential spreads from the nerve along the sarcolemma (muscle cell membrane), it penetrates deep into the muscle cell through the sarcoplasm (cytoplasm of muscle cell), and releases CALCIUM from the intracellular stores.CALCIUM triggers the binding of myosin to the actin filament next to it forming CROSS BRIDGES.
For this to occur, ACTIN BINDING SITE has to be made available. TROPOMYOSIN is a protein that winds around the chains of the actin filament and covers the myosin-binding sites to prevent actin from binding to myosin. The first step in the process of contraction is for calcium ions to bind to troponin so that tropomyosin can slide away from the binding sites on the actin strands.
Answer:
DNA.
Explanation:
Chromosones use a molecule called DNA to carry genetic information. A DNA exists in a cell's nucleus within structures named chromosones.
Good luck~!
