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.

_________ threshold is also called the ________ threshold, the point at which lactic acid produced in muscles begins to accumula
Ne4ueva [31]

Answer:

1. Anaerobic

2. lactate

3. Aerobically

Explanation:

During excessive muscular activities such as a marathon, lactate fermentation occurs in muscles to serve as a source of ATP to sustain muscle contraction. The lactate produced during lactate fermentation is removed aerobically from muscles. Lactate threshold or anaerobic threshold refers to the intensity of physical activity that produces the blood lactate at a fast rate than its removal.

Increased intensity of exercise or physical activity increases lactate production. As the intensity reaches the point at which lactate cannot be removed from the body fast enough, it is accumulated and causes fatigue in muscles. Therefore, the lactate threshold is the upper limit that can be sustained aerobically by the body without any accumulation of lactate.
