The two enzymes that help in the generation of NADPH which is essential for fatty acid synthesis are the Glucose-6-phosphate-dehydrogenase(G6PDH) and the Malic enzyme.
NADPH is predominantly produced by the pentose phosphate pathway, either directly by the malic enzyme as it oxidized malate to pyruvate or indirectly through the glucose-6-phosphate dehydrogenase.
NADP+ is used to make NADPH. The pentose phosphate pathway, which is catalyzed in the first stage by glucose-6-phosphate dehydrogenase (G6PDH), is the main source of NADPH in mammals and other non-photosynthetic organisms.
From glucose, the pentose phosphate pathway also generates pentose, a crucial component of NAD(P)H.
However, the Entner-Doudoroff route is also used by some bacteria, and NADPH generation is unaffected.

Answer and Explanation:
Eukaryotic and prokaryotic cells share the presence of:
- cytoplasm, in which their organelles are dispersed.
-the cell membrane, which covers the cell by shaping and regulating the passage of substances (in and out of it).
- ribosomes, are the place where proteins are synthesized.
In addition, both cells possess DNA although this is not the same in both. In the eukaryotic cell it is linear and is within the nucleus, while in the prokaryotic cell it is circular and does not have a true nucleus that protects it.
I would select B or C as the answer because i have no idea what the other ones are :)
With every other lever 10% of the energy with be transferred. In this case:
Primary Producers (500)
1) First- level consumer. (50)
2) Second-level consumer. (5)
3) Third- level consumer. (0.5)
Remember the formula is:
(Primary Producer) __units X 10%= __
In this case: 500 units X 10%= 50
Answer: For flowering plants, fertilization occurs through a process known as double fertilization. Unlike most plants, double fertilization enables the new seed to grow into a new plant and have a food source to begin growing. Double fertilization occurs within the female part of a plant, the pistol.
explanation: When pollen is formed by the anther, or male part of a plant, it will blow in the wind or attach to an organism that carries it to the top of the pistol, known as the stigma. Once the pollen attaches to the stigma, the pollen germinates and forms a pollen tube that extends into the ovary. Once formed, two sperm cells will be released and fertilize both the egg and the two polar nuclei of the plant to form the zygote and endosperm, respectfully.
