Maru [420]1 year ago

Urine's specific gravity, which is somewhat greater than that of water, is a crucial physical property.

Characteristics of urine:

  • Osmolarity is typically harder to quantify than specific gravity, which measures the amount of solutes per volume of a solution. Because there are solutes in urine, its specific gravity is always higher than that of pure water (water = 1.0). Since specific gravity is a less precise predictor of urinary solutes, laboratories may now directly detect the osmolarity of urine.
  • Osmolarity, or mOsmol/L, is the measure of how many osmoles or milliosmoles are present in a litre of a fluid. The osmolarity of urine can range from 50 to 100 to 1200 mOsmol/L of water.

Therefore, it is concluded that the correct solution is an option (D), i.e., slightly higher than water.

The complete question is:

An important characteristic of urine is its specific gravity or density, which is ________.

A. the same as water

B. less than water

C. much higher than water

D. slightly higher than water

1. List and describe three factors that could possibly affect enzyme activity. 2. Why is it important that cells contain catalas
marta [7]

Answer:

1. Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

2. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS). It catalyzes the decomposition of hydrogen peroxide to water and oxygen.

3. Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate. ... Extreme pH values can cause enzymes to denature.

4. Enzymes are biocatalysts and because of their remarkable properties, they are extensively used in medical diagnosis. ... They provide insight into the disease process by diagnosis, prognosis and assessment of response therapy.

5. The small intestine is a major site for chemical digestion and absorption of key food components, such as amino acids, peptides, and glucose for energy. There are lots of enzymes released in the small intestine and from the nearby pancreas for digestion.

6. Purified human pancreatic alpha-amylase (alpha-1,4-glucan 4-glucano-hydrolase, EC 3.2. 1.1) was found to be stable over a wide range of pH values (5.0 to 10.5) with an optimal pH for the enzymatic activity of 7.0.

Explanation:

1. Factors Affecting Enzyme Activity

Knowledge of basic enzyme kinetic theory is important in enzyme analysis in order both to understand the basic enzymatic mechanism and to select a method for enzyme analysis. The conditions selected to measure the activity of an enzyme would not be the same as those selected to measure the concentration of its substrate. Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

2. Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals). It catalyzes the decomposition of hydrogen peroxide to water and oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS).

4. for clinical applications. Enzymes are the preferred markers in various disease states such as myocardial infarction, jaundice, pancreatitis, cancer, neurodegenerative disorders, etc. They provide insight into the disease process by diagnosis, prognosis and assessment of response therapy.

5. Amylase. Amylase is a digestive enzyme that acts on starch in food, breaking it down into smaller carbohydrate molecules. ... First, salivary glands in your mouth make salivary amylase, which begins the digestive process by breaking down starch when you chew your food, converting it into maltose, a smaller carbohydrate.

6. Purified human pancreatic alpha-amylase (alpha-1,4-glucan 4-glucano-hydrolase, EC 3.2. 1.1) was found to be stable over a wide range of pH values (5.0 to 10.5) with an optimal pH for the enzymatic activity of 7.0.

In the electron transport system
antoniya [11.8K]

Answer:

A. NADH and FADH2 both donate electrons at the same location.

Explanation:

In the respiratory chain, four large protein complexes inserted into the mitochondrial inner membrane transport NADH and FADH₂ electrons (formed in glycolysis and the Krebs cycle) to oxygen gas, reducing them to NAD⁺ and FAD, respectively.

These electrons have great affinity for oxygen gas and, when combined with it, reduce it to water molecules at the end of the reaction.

Oxygen gas effectively participates in cellular respiration at this stage, so its absence would imply interruption of the process.

NADH and FADH₂ electrons, when attracted to oxygen, travel a path through protein complexes, releasing energy in this process.

The energy released by the NADH and FADH₂ electrons in the respiratory chain in theory yields <u>34</u> <u>ATP</u>, however, under normal conditions an average of 26 ATP molecules is formed.

If we consider that these 26 molecules are added to the two ATP formed in glycolysis and two ATP formed in the Krebs cycle, it can be said that cellular respiration reaches a maximum yield of 30 ATP per glucose molecule, although theoretically this number was 38 ATP per glucose molecule.
