Which type of bond joins the cooh group of one molecule to the nh2 of another molecule? a. 1-4 glycosidic bond b. ester bond c. hydrogen bond d. peptide bond

D. Peptide bond

Explanation:

The reaction between one amino acid and another is

The bond that joins the two amino acids is called a peptide bond.

A. is wrong. A 1,4-glycosidic bond is formed between two carbohydrate units.

B.  is wrong. An ester bond is the characteristic feature of fats.

C. is wrong. Hydrogen bonds are intermolecular attractive forces among molecules

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.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
