Answer:
Lactate: fermentation in human muscle
Ethanol: fermentation in yeast and bacteria
Acetyl CoA: aerobic oxidation
Explanation:
Lactate is produced in lactic fermentation in human muscle. Lactic fermentation in muscle cells is a process that occurs alternatively, in situations where the body does not perform aerobic respiration. Considered a short-term metabolic device, activated when the body is subjected to intense physical effort under conditions of low muscular oxygenation.
Alcoholic Fermentation, also known as ethanol fermentation, is the anaerobic pathway performed by yeast and some bacteria, in which simple sugars are converted to ethanol and carbon dioxide. Yeasts usually function under aerobic conditions, either in the presence of oxygen, but are also capable of functioning under anaerobic conditions, or in the absence of oxygen. When oxygen is not readily available, fermentation alcoholic beverages occur in the yeast cell cytoplasm.
Acetyl CoA results from aerobic oxidation. This process occurs in mitochondria during cellular respiration, where pyruvate, the product of glycolysis, can be substituted, and often is, by fatty acids. This is because pyruvic acid is used to form a compound called Acetyl Coenzyme A or Acetyl CoA. In this sense, Acetyl CoA can also be produced by the degradation of fatty acids by a reaction called β oxidation.
1.) Neurons, they transmit nerve impulses<span>.
2.) </span>Neuroglial cells, non-conducting cells of the nervous tissue.
The correct answer is c trachea
Answer:
Whales are mammals and do not have gills, so they cannot take the dissolved oxygen that is in the water and turn in into a oxygen that they can breath.
Explanation:
Answer: b. Muscles
A metazoa is a division of animal kingdom that includes all animals expect protozoa and sponges. Metazoa division includes multicelluar animals, which exhibit highly differentiated cells. They have muscular and nerve system and well coordinated tissues and organs. Locomotion requires a coordination activity of muscular, skeletal and neural system. It is mainly achieved by contraction and relaxation of muscles that occurs due to specialized muscle proteins named as actin and myosin which receives signals from nerves.
Hence, locomotion in metazoa is due to contraction of muscles.
