lactate: fermentation in human muscle ethanol: fermentation in yeast and bacteria acetyl coa: aerobic oxidation (in the presence of oxygen, human cells carry out aerobic respiration, which yields acetyl coa. in the absence of oxygen, human cells can carry out lactic acid fermentation, which yields lactate. yeasts and many bacteria carry out alcohol fermentation, which takes place under anaerobic conditions, and produces ethanol)

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.

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
