c. Glucose and ATP are produced in glycolysis and used in fermentation.

Glycolysis is the process of breaking down glucose to produce energy. It generates two pyruvate molecules, ATP, NADH, and water. The process occurs in a cell's cytoplasm and does not require oxygen. It can be found in aerobic and anaerobic organisms.

Glycolysis is a cytoplasmic pathway that converts glucose into two three-carbon compounds while producing energy. Phosphorylation traps glucose with the help of the enzyme hexokinase.

Fermentation is a metabolic process that involves the action of enzymes to produce chemical changes in organic substrates. It is narrowly defined in biochemistry as the extraction of energy from carbohydrates in the absence of oxygen. Fermentation is an ancient method of food preservation. The method is still used today to make wine, cheese, sauerkraut, yogurt, and kombucha.

1. The following statement is similar to those you might see on exams. Write a paragraph of 3-5 sentences describing 1) whether
yanalaym [24]

Answer:

The oxygen dissociation curve represents the percentage saturation of Hb with oxygen at different partial pressure of oxygen. The different partial pressures gives sigmoid shapes to the curve. When this curves shifts to right, it  indicates  low affinity or binding of oxygen by the Hb. it also indicates the unloading or releases of Oxygen by Hb molecules at condition of low pressure. e,g in the muscles during strenuous exercise.However, when the curve shifts to the left, this indicate high affinity for oxygen, great binding, at high partial pressure of oxygen.e,g in the lungs to take oxygen and releases CO2.

Therefore in this scenario, the statement -. <u>During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right.</u> is correct. because oxygen is needed by the muscles therefore ,oxygen should be less binded by Hb,  decrease affinity and easily unloaded to muscles.

<u>The statement </u>This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 into hemoglobin in the lungs is wrong.

As explained above the rightwards shift indicated low affinity of Hb for oxygen(unloading)and  favours unloading at the muscles because during strenuous exercise the partial pressure of oxygen is very low(but that of CO2 high) in the muscles which favours low oxygen molecules  binding by Hb, and easy release to respiring cells.

Pavel [41]

Answer:

C. Acquired herniations of the muscular colon wall mucosa and submucosa

Explanation:

Hernia refers to the development of outgrowth or protrusion of all or part of the organs through their cavity walls or membrane. Diverticulosis is herniation of mucosa and submucosa of the wall of the colon. Diverticulosis is one of the conditions caused by the imbalance of homeostasis. Many sac-like outgrowths develop in the wall of the colon. The outgrowths are in the form of pouches and are called diverticula.

The out-pouching occurs where the muscularis layer of the wall of the colon has weakened. The people with diverticulosis may have no symptoms and no complications. However, when diverticulosis causes inflammation, the person experiences several complications such as pain, vomiting, nausea, etc.

Why would the green part of a variegated test positive when treated with iodine solution?​
MatroZZZ [7]
This is your perfect answer.
Variegated leaves have green parts (where the cells contain chlorophyll) and white parts (where there is no chlorophyll). Only the parts that were green become blue/black with iodine solution, showing the importance of chlorophyll in photosynthesis. ... This is evidence that chlorophyll is required for photosynthesis.
