Why would your muscle cells switch to anaerobic respiration if it doesn't produce as much ATP?
ser-zykov [4K]

Answer:

Lack of oxygen

Explanation:

There are two mechanisms for energy production (glucose breakdown), aerobic and anaerobic. When adequate amounts of oxygen are present, aerobic mechanism is used. However, when there is insufficient oxygen, such as during exercise, the anaerobic mechanism is used.

Two cell divisions mitosis or meiosis
Troyanec [42]
Cell division is the process by which a parent cell divides into two or more daughter cells.[1]Cell division usually occurs as part of a larger cell cycle. In eukaryotes, there are two distinct types of cell division: a vegetative division, whereby each daughter cell is genetically identical to the parent cell (mitosis),[2] and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes(meiosis). Meiosis results in four haploid daughter cells by undergoing one round of DNA replication followed by two divisions. Homologous chromosomes are separated in the first division, and sister chromatids are separated in the second division. Both of these cell division cycles are used in the process of sexual reproduction at some point in their life cycle. Both are believed to be present in the last eukaryotic common ancestor.

Prokaryotes (bacteria) undergo a vegetative cell division known as binary fission, where their genetic material is segregated equally into two daughter cells. All cell divisions, regardless of organism, are preceded by a single round of DNA replication.

For simple unicellular microorganisms such as the amoeba, one cell division is equivalent to reproduction – an entire new organism is created. On a larger scale, mitotic cell division can create progeny from multicellular organisms, such as plants that grow from cuttings. Mitotic cell division enables sexually reproducing organisms to develop from the one-celled zygote, which itself was produced by meiotic cell division from gametes. After growth, cell division by mitosis allows for continual construction and repair of the organism.[3] The human body experiences about 10 quadrillion cell divisions in a lifetime.[4]

The primary concern of cell division is the maintenance of the original cell's genome. Before division can occur, the genomic information that is stored in chromosomes must be replicated, and the duplicated genome must be separated cleanly between cells.[5] A great deal of cellular infrastructure is involved in keeping genomic information consistent between generations.

What changes in the food industry created the Western diet and can be linked to chronic diseases such as coronary heart disease,

                   increasing production of cheap calories of Sugar and Triglycerides  for use in food products

The attempt by farmers to maximize profit prompted them to give hormones e.g streroids to  animals to increase their  biochemical reactions therefore the the products yields e.g they  are  giving  steroids  to poultry  to  improve chicken, eggs production;and  to  cattle for improved beef and milk production.

In order to obtain maximum sugar and fats productions, cheap calories  forms of there  are being  produced. e,g fructose, maltose. if  maltose  is consumed in excess  it leads to  obesity, while fructose increases the level of cholesterol.These products  requires a lot of processing with different chemical products which leads to health problems after consumption
