<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.
Answer:
D is the correct option
Explanation:
expansion of water is not significant over day night temperature
Answer:
transcription factors bind to the promoter, and RNA polymerase is then recruited to begin transcribing the gene
Explanation:
The transcription process in eukaryotes happens in 3 stages:
- Initiation
- Elongation
- Termination
The initiation of transcription starts when a set of proteins called the transcription binds to the promoter region of a gene on the coding strand of DNA. Thereafter, the RNA polymerase enzyme binds to the promoter region thereby opening up the double helix structure of the DNA in anticipation of transcription.
During elongation, RNA nucleotides are added to the growing RNA strand in 5' to 3' direction with the DNA unwinding and winding back as the polymerase moves along the coding strand in 3' to 5' direction.
Transcription terminates when the RNA polymerase gets to the end of the gene being transcribed signalled by a sequence of DNA known as the terminator.
<em>Hence, in the illustration, the correct answer would be that the transcription factors bind to the promoter, and RNA polymerase is then recruited to begin transcribing the gene.</em>
Assuming that Element X is neutral or the atom of element X is neutral or uncharged it will possess the same number of electrons which is 80.
The synthesis of fatty acids starts with a preparatory step in which acetyl-CoA is mediated from mitochondria to the cytosol. However, it cannot pass through the membrane, so it is transported as citrate, which is cleaved to acetyl CoA and oxaloacetate.
In the cytosol, acetyl CoA is transformed to malonyl CoA, that is, a three carbon compound. Fatty acid synthesis starts with the conduction of acetyl group from acetyl CoA to fatty acid synthase.
Two carbon groups, supplied to malonyl CoA, are supplemented to the developing acyl chain in a series of steps involving condensation, reduction, and dehydration reactions. Elongation of the fatty acid chain ceases at 16 carbon atoms, after seven cycles, as the free free fatty acid is discharged.
