The circuit shown in the figure contains two ideal diodes \( D_1 \) and \( D_2 \). If a cell of emf 3V and negligible internal resistance is connected as shown, then the current through \( 70 \, \Omega \) resistance (in amperes) is: 
Photosynthesis in higher plants involves the following processes:
This process occurs in the absence of light in the stroma of the chloroplasts. The following cycles are involved in the process:
