Why does breathing into a paper bag decrease effects of hyperventilation?
The major symptoms caused by hyperventilation are caused by the decrease in arterial carbon dioxide (CO2) caused by hyperventilation. Breathing into a bag causes you to rebreathe CO2 and raise the CO2 level, which causes the symptoms to go away. The danger of this is that you can actually raise the CO2 level too much and cause other problems.
What job does the electron transport chain accomplish in order to drive the formation of ATP?
The electron transport chain helps to create a proton gradient across the inner mitochondrial membrane. This gradient drives the movement of protons back across the membrane through ATP synthase, which then synthesizes ATP from ADP and inorganic phosphate.
What are the balanced chemical equations for lactic acid fermentation?
An organic acid with the chemical formula CH3CH (OH). COOH. Lactic acid is a product of anaerobic glycolysisLactic acid system An anaerobic energy system in which ATP is manufactured from the breakdown of glucose to pyruvic acid. The acid is then converted to lactic acid. High-intensity activities lasting up to about two or three min use this energy system during which the reduction of nicotinamide adenine dinucleotide (NAD) is coupled with a net production of two ATP molecules for each glucose molecule metabolized.
What macromolecules are present in saliva?
Saliva contains water, electrolytes, mucus, enzymes (such as amylase for breaking down carbohydrates), and antibacterial compounds. These macromolecules help with digestion, lubrication, and protection within the oral cavity.
How does water excreted in the body?
human body requires more amount of water for all metabolic process. water plays many crucial roles in body metabolism and mechanism. usally human body consumes 15 lit / day internally and its recommended to take 3 Lits of water/day. The kidney distilled the blood and excrete the ammonia waste with water. Minimum 1.5 Lit of water excreted per day via the kidney in the form of Urine. Sweat also excrete small amount of water from the body to maintain the body temperature.
Is acetic acid a bio buffer or not?
Yes, acetic acid is a weak acid commonly used in biological buffers due to its ability to resist pH changes. It is often used in buffer solutions to maintain a stable pH in biological experiments and biochemical reactions.
GLUCOSE IS VERY DEFINITELY POLAR WITH OH (HYDROXYL) GROUPS ALL OVER IT, WHICH ARE THEMSELVES VERY POLAR. THE MOLECULE IS ALSO VERY UNSYMMETRICAL WHICH TENDS TO MAKE IT POLAR. THE FACT THAT GLUCOSE IS EXTREMELY SOLUBLE IN WATER (ANOTHER POLAR SUBSTANCE) SHOWS THAT GLUCOSE IS POLAR SINCE "POLAR DISSOLVES IN POLAR" AND "NONPOLAR DISSOLVES IN NONPOLAR" (LIKE WAX AND GASOLINE)
How does aspirin dissolve in carbohydrate solution?
Aspirin is a weak acid that can dissolve in water due to its polar structure and hydrogen bonding. When aspirin is added to a carbohydrate solution, it can form hydrogen bonds with the hydroxyl groups of the carbohydrate molecules, helping it dissolve more readily in the solution.
The energy for photosynthesis reactions comes from sunlight. These reactions take place in the chloroplasts of plant cells, specifically in the thylakoid membrane where pigments like chlorophyll capture light energy to drive the process of photosynthesis.
Is sugar hydrophilic or hydrophobic?
Hydrophilic molecules are those that dissolve in or interact with water. Hydrophilic molecules include carbohydrates, proteins, nucleic acids, salts and metabolic molecules like glucose and amino acids.
The fatty component of lipids [fats and oils], the -CH2- tail, is strictly hydrophobic.
How much light does the jungle get a day?
The amount of light a jungle receives can vary depending on factors like the density of the canopy, time of year, and geographical location. On average, jungles typically receive about 2-5% of the sunlight that reaches the top of the canopy, resulting in dappled or filtered light conditions throughout the day.
How many glucose monomers are there in a single starch molecule?
A single starch molecule contents few thousands glucose monomers in single molecule.
Glucose oxidizes very quickly, and creates a silver mirror layer between the glucose solution and the Tollens' reagent. This is because of how the ketose reacts and reduces the silver molecules in Tollen's reagent.
What is the functional difference between enhancers and promoter proximal elements?
Enhancers are at considerable distances from the promoter and can be moved or inverted and still function. Promoter-proximal elements are close to the promoter and their position and orientation must be maintained.
What does it mean to say that a protein functions by a lock and key model?
The lock and key model suggests that proteins interact with other molecules in a specific and precise manner, similar to how a lock only fits with a specific key. In this model, the protein (lock) is complementary in shape to the molecule it interacts with (key), ensuring a precise and selective binding interaction.
Why is chemical disequilibrium essential for life?
Chemical reactions need to keep moving in one direction or the other-- either giving off energy, or using it up. If chemical reactions were at equilibrium, no energy is being absorbed nor given off, therefore nothing would happen.
3 basic components of a nucleotide?
A nucleotide is composed of three basic components: a phosphate group, a five-carbon sugar (either deoxyribose or ribose), and a nitrogenous base (either adenine, guanine, cytosine, or thymine/uracil).
Gastrin is a hormone produced by the stomach that stimulates the release of gastric acid, aiding in the digestion of food. It also plays a role in regulating the emptying of the stomach and the movement of food through the digestive tract. Abnormal levels of gastrin can lead to conditions like gastritis and peptic ulcers.
What substances can a plant use PGAL to make?
Plants can use PGAL (phosphoglyceraldehyde) to make various organic compounds such as glucose for energy production, cellulose for cell walls, and lipids for cell membranes. Additionally, PGAL can be used in the production of amino acids and other compounds essential for plant growth and development.
What makes cellulose different from starch?
cellulose has beta1-4 linkages and is not branched and has only one reducing end so it is much harder to break down hence why it is used for structure. and starch is highly branched and has many reducing ends, it is made of alpha 1-4 and alpha 1-6 linkages. The alpha 1-6 give the branching leading to many reducing ends which is why it is used for storage
What does chloroplast DNA resemble?
Chloroplast DNA (cpDNA) resembles bacterial DNA in terms of size, structure, and gene content. This is because chloroplasts are believed to have originated from an ancient endosymbiotic event where a photosynthetic bacterium was engulfed by a eukaryotic cell.
What is the function of unsaturation in the hydrocarbon tails of membrane lipids?
Unsaturation in the hydrocarbon tails of membrane lipids introduces kinks in the structure, which prevents the lipids from packing tightly together. This increases the fluidity of the membrane, allowing it to remain flexible and dynamic at different temperatures.
Why is photosynthesis essential to the lives of animals on earth?
Photosynthesis is essential because it produces oxygen, which animals need for cellular respiration to generate energy. It also produces glucose, which serves as a primary source of food for many animals in the form of plants. Without photosynthesis, oxygen levels would decrease, and food sources for animals would be severely limited.
What is a simple way to explain photosynthesis?
Photosynthesis is the process by which a plant uses a combination of its chemicals and sunlight to split water into H and O. The H is used by the plant to build more complex chemicals, and the O is a waste gas. Chlorophyll is the important chemical the green plants use to photosynthesize. Red and Brown seaweeds use different chemicals with different colours.
Because if enzymes are exposed to very high temperature they get damaged and don't work properly but they also need pretty high temperature to work to their maximum quickness. Body temperature is PERFECT!
