Maltose is produced instantly when amylase reacts with starch.
Starch is a polysaccharide molecule made of glucose units. The chemical formula of the starch is written as (C₆H₁₀O₅)ₙ. The starch consists of amylose and amylopectin. The glucose units in this starch are linked with the help of two kinds of bonds α 1,4 glycosidic linkages and α 1,6 glycosidic linkages.
This starch molecule is first hydrolyzed into shorter polysaccharides, dextrins, and maltose with a help of an enzyme called amylase. The maltose can be further hydrolyzed into glucose units with the help of the maltase enzyme.
Therefore, the blank can be filled with maltose.

Answer:
When a muscle cell contracts, the myosin heads each produce a single power stroke.
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, <em>tropomyosin is obstructing binding sites for myosin on the thin filament</em>. 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 liberated. Myofilaments slide impulsed by chemical energy collected in myosin heads, <u>producing a power stroke</u>. 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.

Explanation:
Vascular plants transport water and nutrients using the vascular bundles, xylem and phloem. Xylem transports the former and phloem the latter
The main component in three investigations is that in my opinion The common denominator of the fact that they are all three still investigations.
Answer:
