Answer: The acetyl CoA used in the first step is immediately returned to the process of acetyl CoA used in the first step is immediately returned to the process of acetyl CoA formation.
The Kreb's cycle is also known as citric acid cycle or tricarboxylic acid cycle is the process which involves a series of reaction which is required to breakdown food into form of energy that a cell can use. The cycle starts in the mitrochondria of the cell where glycolysis takes place utilizing two molecules of pyruvic acid to produce energy molecules in the form of ATP. The end products of Kreb's cycle includes 2 ATP, 10 NADH, 2 FADH₂ and oxaloacetic acid molecules per 2 molecules of pyruvic acid. NADH and FADH₂ are accepted by the electron transport chain. The final product which is left after kreb's cycle is oxaloacetic acid. The Kreb's cycle is called as a cycle because oxaloacetic acid is the molecule required to accept an acetyl-CoA molecule and start another turn of the cycle.
Answer:
Aerobic cellular respiration occurs after glycolysis when oxygen is present. After glycolysis if oxygen is not present anaerobic fermentation takes place; either ethyl alcohol found in alcohol and yeast or lactic acid found in muscles of humans and animals
Answer:
E. combined oral contraceptives
Explanation:
Oral contraceptives will decrease a woman's risk of developing ovarian and endometrial cancer. The earlier, higher dose oral contraceptive pills have been linked to a slight increase in breast cancer, but not the most recent lower dose pills. Women who use oral contraceptive pills have a slightly higher risk of developing cervical intraepithelial neoplasia, but their risk of developing PID, endometriosis, benign breast changes and ectopic pregnancy are reduced. Both hypertension and thromboembolic disorders can be a potential side effect from using oral contraceptive pills. Condoms and intrauterine devices will not lower her risk of ovarian cancer.
The influence of Christianity
Tattoo is a permanent mark or
design made on the body by inserting pigment through ruptures in the skin. Decoration
is the most common motive for tattooing. In Polynesia, tattooing was a cultural
practice that transcended time and space but overtime, tattooing gradually lost
its importance in the cultural routine of the Polynesian people as the Christian
missionaries forcibly paved the way for a relinquishing of ancient customs in
many regions thereby eradicating tattooing in Polynesia.
