What happens to contraction of a muscle cell if some of the Ca2+ that was released during a contraction is still in the cytoplas
Kazeer [188]
<h2>Muscle contraction in cytoplasm </h2>

Explanation:

  • Calcium stays in the sarcoplasmic reticulum until discharged by an improvement. Calcium at that point ties to troponin, causing the troponin to change shape and expel the tropomyosin from the coupling destinations. Cross-connect stick proceeds until the calcium particles and ATP are never again accessible.
  • ATP is basic to get ready myosin for official and to "revive" the myosin.
  • When the actin-restricting destinations are revealed, the high-vitality myosin head overcomes any issues, framing a cross-connect. When myosin ties to the actin, the Pi is discharged, and the myosin experiences a conformational change to a lower vitality state. As myosin consumes the vitality, it travels through the "power stroke," pulling the actin fiber toward the M-line.

During respiration, a seed metabolizes sugars. what is the source of the sugar metabolized by the seed?
pashok25 [27]

The source of the sugar metabolized by the seed is photosynthesis.  

The procedure used by plants to transform light energy into a chemical form of energy is known as photosynthesis. The chemical energy can afterward be discharged to fuel the plants to perform their activities.  

During photosynthesis, carbon dioxide and water can be combined in the existence of chlorophyll and sunlight to generate oxygen and glucose (carbohydrates). However, the prime component generated in the procedure is glucose (sugar) that is the molecule, which generates energy to mediate the activities of the cell.

Choose the term that correctly describes the relationship between these two sugar molecules
DIA [1.3K]

Answer;

-Structural isomers.

Explanation;

-Isomers are molecules that have the same molecular formula, but have a different arrangement of the atoms in space.

-Structural Isomers are molecules which have the same molecular formula but have different connectivities. That is; the molecules have the same molecular formula, but their atoms have different arrangements or bonds.

-For example, butane and isobutane are structural isomers, also called chain isomers. In chain isomers, the carbon atoms are connected in different orders. Isobutane and butane have a molecular formula of C4H10.

Explanation:

At present the Koala are found in several states of Australia such as  

a) Queensland

b) NSW

c) Victoria

d) South Australia  

Though the Koala is found on the eucalyptus trees  of the  temperate rain forest , they are only found in Australian geographies . There are several other place on planet earth where there is rainforest with eucalyptus trees and temperate climate, even though the Koalas are limited to Australia.
