Cells must use energy to move a substance against a concentration gradient i.e., from a compartment with a low concentration of

garik1379 [7]

Answer:

Transport of sodium ions out of the cell

Transport of potassium into the cells

Transport of calcium ions out of cell

Transport of calcium ions OUT OF the cytoplasm of a cell and INTO an organelle that has a high concentration of calcium ions.

Explanation:

In general the concentration of sodium ion is higher outside the cell in the extracellular fluid and the concentration of potassium ion is higher inside the cell.

During an active transport, a cell uses energy to move molecules against the gradient as a part of primary active transport. In the secondary active transport, the molecules move as per the electrochemical gradient established by the primary active transport.

In primary active transport, sodium ion moves out of the cell and potassium ion moves into the cell through the assistance of sodium potassium pump. In order to maintain the stability, calcium ion from the sarcoplasmic reticulum is pumped out of the cell

Hence , the correct answers are

Transport of sodium ions out of the cell

Transport of potassium into the cells

Transport of calcium ions out of cell

Transport of calcium ions OUT OF the cytoplasm of a cell and INTO an organelle that has a high concentration of calcium ions.

sertanlavr [38]

Answer:

The correct answer is B. DNA helicase first unwinds the double helix around the +1 site.

Explanation:

The helicase is an enzyme that specifically breaks the hydrogen bonds of the bases in the transcription process. As E. Coli is a prokaryote, then, the transcription only occurs in one point of the circular DNA. The promoter region indicates where the DNA polymerase has to start replicating and the Topoisomerase unwinds the parts of the DNA that are being excessively twisted because of the separation of the two strands.
