Task 2 Investigating Respiration

Its purpose is to break down hydrogen peroxide as hydrogen peroxide is a waste product that is poisonous to cells. Found extensively in organisms that live in the presence of oxygen, catalase prevents the accumulation of and protects cellular organelles and tissues from damage by peroxide, which is continuously produced by numerous metabolic reactions. Its purpose is to break down hydrogen peroxide, which is a waste product in cellular activity and are poisonous to cells. If it were not for Catalase, the hydrogen peroxide will build up in the bodies and kill us. Catalase speeds up the decomposition of hydrogen peroxide into harmless water and oxygen gas.

A patient is treated depending on its cause. For alkalosis caused by hyperventilation, breathing into a paper bag allows you to keep more carbon dioxide in your body, which improves the alkalosis. If your oxygen level is low, you may receive oxygen. Medicines may be needed to correct chemical loss such as chloride and potassium (Respiratory alkalosis, 2014) Because of their delicate fluid and electrolyte status the elderly are at risk for metabolic

Hypothesis If a person exercising is working harder, by performing an exercise like running or sprinting, their heart rate and CO2 production will be higher, measured by higher BPM and lower time taken to turn the BTB yellow, than a person who is sitting or walking, because muscles need more energy to perform the more strenuous tasks, and the higher heart rate and CO2 production will indicate a higher cellular respiration rate. Experimental Design IV: Exercise. Sitting, walking, running, and sprinting up the stairs will be an increasing amount of work for the person’s body, showing a trend toward harder work DV: CO2 measured by BTB, HR measured in BPM, both will show increase in intensity and cellular respiration. Control: Sitting person will provide a baseline against exercise

If the ratio is close to 1.0, the subject is most likely in extreme exercise and utilizing only carbohydrates. The ratios of oxygen and carbon dioxide are shown through the oxidation reactions of both fat and carbohydrates. It is possible to calculate an RER higher than 1 because of hyperventilation in the lungs [2]. The respiratory quotient (RQ) is the measurement of CO2 and O2 in the tissues at the cellular level. The most accurate way to determine RQ is through the bicarbonate buffer reaction where the amount of hydrogen ions show metabolism.

The process of cellular respiration, cells extract the energy stored in the glucose molecule (Campbell & Reece, 2005). The molecule is a sugar that provides major fuel for cellular to work. But the carbon skeleton works on the row material for synthesis of all different verities of small organic molecules. For example amino acids and fatty acids. Such sugar molecules that are not immediately used are incorporated into disaccharides and polysaccharides.

Before the water reach to the consumer 70% of the permeate water goes to potabilization or remineralization while 30% goes the demineralization. In potabilization plant four chemicals are added which are: Sodium hypochlorite It is added for final disinfection of treated water Sodium fluoride This chemical must be existed in the potable water because when it dissociate fluoride is produced as shown in the chemical reaction: NaF → 〖Na〗^++ F^- The fluoride used to protect the teeth in two ways: Protection from demineralization - when bacteria in the mouth combine with sugars they produce acid. This acid can erode tooth enamel and damage our teeth. Fluoride can protect teeth from demineralization that is caused by the acid. Remineralization

The respiratory system supplies oxygen to the blood and removes the carbon dioxide out of the blood. When the human heart has blood that is low in oxygen and high in carbon dioxide, it pumps that blood to our lungs through the pulmonary arteries. However when our lungs expand and get new fresh air from the surroundings, that oxygen is then transferred to the blood which is low in oxygen which also sends some of the new carbon dioxide breathed in to our lungs. As the blood now has fresh oxygen it is sent back to the heart and the heart pumps this clean blood throughout the entire

What they actually do: Petroleum derived ingredients are pore clogging components, which work as a delivery agent, meaning they trap all other junk in the product deeper into the pores. Sometimes they may come with such hazardous ingredients as the 1,4-dioxane, a carcinogen and neurotoxin... Parabens Names: acnemethylparaben, propylparaben, ethylparaben, butylparaben What they are supposed to do: Supposedly they make the mold growth stop and also extend the shelf life of the product... What they actually

Research Question: To investigate and compare how different temperature (5℃, 15℃, 25℃, 35℃, 45℃) can affect the concentration of carbon dioxide in soda water through titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌ H2CO3 The popping sound we hear when we open the can of fizzy drink, the bubbles and sparkle we see in the soft drink, and the feeling of bubble popping on your tongue, all of these are due to carbon dioxide escaping from solution.

Yeast extract in the agar supply sources of nitrogen, carbon, and vitamin for the metabolism of organisms. Xylose, Lactose, and Sucrose acts as the fermentable carbohydrate sources. Sodium Deoxycholate acts as the selective agent while Sodium Chloride provides buffering capacity. Phenol red is used as the indicator. The selective agents in the agar such as Sodium Thiosulfate and Ferric Ammonium Citrate support visualization of hydrogen sulfide production under alkaline conditions.

Once hydrogen and the baking soda ions bump into each other, they form carbonic acid (H2CO3). Carbonic acid decays to form carbon dioxide and water. The formation of the carbon dioxide causes the fizzing action seen in the experiment. It is shown in the equation: H+ (aq) + HCO3 - (aq)
