inorganic fluoride inhibits enolase. in an anaerobic system that is metabolizing glucose as a substrate, which compound would you expect to increase in concentration following the addition of fluoride?

Answers

Answer 1

Enolase is inhibited by inorganic fluoride. When fluoride is added to an anaerobic system that is metabolizing glucose as a substrate, the compound 2-phosphoglycerate is expected to increase in concentration. The correct answer is option(a).

Enolase is a glycolytic catalyst, that catalyzes the bury-adaptation of 2-phosphoglycerate to phosphoenolpyruvate. Altered expression concerning this something that incites activity is repeatedly noticed in tumors and gives reason for the Warburg effect, an adjusting response of swelling containers to hypoxia.

Enolase is something that incites activity being the reason for the erratic change of D-2-phosphoglycerate (2PGA) and phosphoenolpyruvate (PEP) in glycolysis and gluconeogenesis, two metabolic pathways that are frequently essential for cellular function. Glucose is a plain carbohydrate accompanying the microscopic recipe C₆H₁₂O₆.

two newly identified microorganisms are under investigation in your laboratory. you've been growing them in liquid media containing glucose and both strains thrive. but when transferred to media containing only acetate, one strain survives but the other strain dies. what predictions can be made from these results?

Answers

Two newly identified microorganisms are acetate  and cellular carbon.

What is acetate?

Acetic acid comes in salt or ester form as acetate. The most typical component of biosynthesis, including the production of fatty acids, is acetate. A proton is taken out of the carboxy group of acetic acid to produce acetate, according to the NCI Thesaurus (NCIt).

What is glucose?

Known also as glucose, blood sugar is the main sugar found in your blood. Your body uses it as its main source of energy, and it comes from the food you eat. The glucose in your blood is used as fuel by all of the cells in your body. Diabetes symptoms include excessively high blood sugar levels.

On transferring onto the media containing acetate  one strain survives that means the strain which survives can carry out glyoxylate cycle because glyoxylate cycle allows cell to utilize  two carbon compound such as acetate  to satisfy  cellular carbon requirement as a source when simple sugars such as fructose and glucose are absent.

Therefore, two newly identified microorganisms are acetate  and cellular carbon.

To become a fossil, an animal must remain buried for thousands or millions of years until it (and the layer around it) turns to rock. hence option a is correct answer.

The record of life preserved in stone monuments is preserved in fossils. Nearly all living things have the ability to leave behind fossils, but typically only the tough components of plants and animals do so. Animals' muscles, skin, and soft internal organs disintegrate quickly and are rarely preserved, but their bones and shells are suitable candidates for fossilization. Soft animals like jellyfish and worms have almost no fossil records. There are several ways that fossils are created, but the majority occur when an animal or plant dies in a wet environment and is buried in mud and silt.

Answers

The phenotypic and genotypic ratio of the offspring will be same and it is 1:2:1.

what is incomplete dominance?

One type of intermediate inheritance in which one allele for a particular trait is not fully expressed over its paired allele is known as "incomplete dominance.

Monohybrid cross was done between the curly and straight hair of dog. Consider, pure breed of the curly hair has CC pair of alleles and that for the straight hair is cc.

Firstly, true-breeding curly (CC) and straight (cc) hair was crossed. The F1­ generation produced a wavy hair with Cc pair of alleles.

Darlene has heavy deposits of plaque containing cholesterol and fats collected on the walls of her main arteries. Darlene has atherosclerosis.

The accumulation of fats, cholesterol, and other substances in and on the artery walls is known as atherosclerosis. This buildup is known as plaque. Plaque can cause arteries to narrow, cutting off blood flow. Atherosclerosis is a thickening or hardening of the arteries caused by plaque buildup in the artery's inner lining. High cholesterol and triglyceride levels, high blood pressure, smoking, diabetes, obesity, physical activity, and consumption of saturated fats are all risk factors.

The symptoms vary according to which arteries are affected and how much blood flow is blocked. Coronary heart disease symptoms include chest pain (angina), cold sweats, dizziness, extreme tiredness, heart palpitations (the sensation that your heart is racing), shortness of breath, nausea, and weakness.

Anaerobic glycolysis, which yields less ATP per cycle, is the main method used by glycolytic fibers to make ATP. As a result, glycolytic fibers lose energy more quickly. The structural components of slow oxidative fibers maximize their capacity to produce ATP via aerobic metabolism.

Anaerobic glycolysis is the main source of ATP for fast glycolytic fibers. They have a lot of glycogen, which allows them to produce ATP quickly. These fibers have extremely few mitochondria due to their dependency on anaerobic metabolism, which results in poor oxygen availability.

Recent protein interaction assays and cell culture studies demonstrate the selectivity of function conferred on either partner by alternative splicing. Insertion of β-neurexin into site 4 selectively promotes GABAergic synaptic function, whereas insertion of neurolysin-1 into site B selectively promotes glutamatergic synaptic function.
