The codon loop.............
Answer:
An extracellular molecule activates a membrane protein, which in turn activates molecules inside the cell.
Explanation:
Signal transduction may be defined as the cellular process in which the signal is transmitted into the cells. The signal transduction results in the detection of the stimuli and the effects generated in the body.
The signal transduction initiates the series of cascade for the signal transmission. The protein is activated by the extracellular molecule and activates the different molecules by the phosphorylation at the different steps of the transduction.
Thus, the correct answer is option (c).
The correct answer for the question is B, ATP contains less potential energy than ADP.
Explanation;
ATP contains more energy potential than ADP , since it has three phosphate bonds unlike ADP which has 2 phosphates.
A. is true; During glycolysis ATP is formed, Glycolysis uses 2 ATP molecules and also generates four ATP molecules which gives a net energy of 2 ATP molecules.
C is true, as plant cells generate ATP during cellular respiration. Cellular respiration is the process in which cells generate energy in form of ATP through oxidative phosphorylation in the mitochondria.
D. is true; ATP is used as a mobile energy carrier molecule by all cells. It used by these cells to fuel all cellular activities.
