Explanation:

Sperm has digestive enzymes called acrosome to digest into the first layer of the cell

Sperm has an elongated shape making it faster to reach the egg

fallopian tube

Human fertilization is the binding of a human egg and sperm, usually occurring in the ampulla of the fallopian tube. The result of this is the production of a zygote cell or fertilized egg.

Zygote cell

After about 6-12 days the fertilized egg travels to the uterus and attaches to the uterus in a process known as implantation. The egg is pushed back towards the uterus by the cilia. The egg must attach to the uterus to become a viable pregnancy.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
