To determine which of the given molecules are electron carrier molecules, follow these steps:
1. List the molecules provided in the question:
- NADP+
- FAD+
- ATP
- ADP
- G3P
2. Identify which of these molecules function as electron carriers. Electron carriers are molecules that transport electrons during cellular respiration and photosynthesis. Common electron carriers include NAD+, NADP+, and FAD.
3. Review each molecule:
- NADP+ (Nicotinamide adenine dinucleotide phosphate) is an electron carrier.
- FAD+ (Flavin adenine dinucleotide) is an electron carrier.
- ATP (Adenosine triphosphate) is the primary energy carrier in cells but not an electron carrier.
- ADP (Adenosine diphosphate) is involved in energy transfer but is not an electron carrier.
- G3P (Glyceraldehyde-3-phosphate) is an intermediate in glycolysis and the Calvin cycle but not an electron carrier.
4. From this analysis, the molecules that are electron carriers are:
- NADP+
- FAD+
Therefore, the electron carrier molecules from the given list are NADP+ and FAD+.
