Summarize the development of a calf fetus during gestation.

Fetal Development of the Beef Calf. One of the most rewarding days for many cow/calf producers is sale day. ... At 24 hours the fetus is a 2-celled embryo; on day 1.5 it is 4-celled, and by day 3 it has reached 8 cells as it travels down the oviduct toward the uterus, entering it between days 5-6

Explanation:

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.
