I'm pretty sure it's Latin, acer means tree and I think rubrum is red
A citric acid cycle is less active when a cell has a high atp/adp ratio and high nadh/nad ratio.
<h3>What is cell and cell theory?</h3>
A cell is the structural and functional unit of life and it the the base of an living organism.
Cell theroy is a scientific theroy that's help to learn how living organisms are made up of cells, that's they are the basic structure unit of all organisms, and that all cells from pre-existing cells.
Prokaryotic cells are single-celled microorganisms known to be earliest on earth.Eukaroyatic cells have a nucleus enclosed within the nuclear membrane and form large and complex organism.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialized it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Therefore,a citric acid cycle is less active when a cell has a high atp/adp ratio and high nadh/nad ratio.

Answer: The correct answer is option D
SECONDARY ACTIVE COUNTER-TRANSPORT
Explanation: Secondary active transport is a type of transport that involves molecules across the cell membrane utilizing or making use of energy in other forms than Adenosine Triphosphate (ATP).
The energy that is being made use of comes from the electrochemical gradient created by pumping ions out of the cell. This can be either via antiport or symport.
Antiport or Counter-transport means that 2 different molecules or ions are being transported at the same time but opposite directions. One of the species is allowed to flow from high concentration to a lower concentration (often Sodium) while the other species is transported simultaneously to the other side.
Example is Na+-H+ counter-transport, the example and advantage of this transporter is clearly seen in the proximal tubules of the kidneys. The mechanism for concentrating H+ is not nearly as powerful as Primary active transport, however it can transport extremely large numbers and thus making it a key in H+ homeostasis in the body.
