How do you test for aerobic respiration?

Limewater turns milky in the presence of carbon dioxide. It can be used to show that exhaled air contains more carbon dioxide than inhaled air. Carbon dioxide dissolves in water to form a weakly acidic solution. Hydrogencarbonate indicator is used to show the presence of carbon dioxide in solution.

How do you prove anaerobic respiration experimentally?

Anaerobic respiration can be experimentally proved by the following activity.

  1. A fermentation tube is filled with 10% sucrose solution and mixed with a small quantity of Baker’s yeast or a few millilitres of suspension of yeast cells.
  2. The open end of the apparatus is plugged with cotton wool.

What is aerobic respiration GCSE PE?

Respiration is the release of energy from glucose in the muscles. When the body is at rest this is aerobic respiration. As you exercise you breathe harder and deeper and the heart beats faster to get oxygen to the muscles.

What is aerobic respiration question answer?

Aerobic Respiration: It is the process of cellular respiration that takes place in the presence of oxygen gas to produce energy from food. This type of respiration is common in most of the plants and animals, birds, humans, and other mammals. In this process, water and carbon dioxide are produced as end products.

How do you measure breathing rate in Igcse?

The rate of breathing can be measured by counting the number of breaths in one minute. The depth of breathing can be measured using a spirometer (a device that measures the volume of air inhaled and exhaled).

Why is soda lime used in an experiment?

so if the air from the jar containing the plant is passed through the soda lime , it will it will be observed that the soda lime water turns milky . hence we can conclude that carbon dioxide is released when plants respire . this is why soda lime is used in the experiment for respiration of plants / animals .

What procedure do you follow to understand anaerobic respiration in your school laboratory?

1) Heat the glucose Solution in a beaker, pour it in a thermos flask. 2) To remove dissolved oxygen from glucose solution by boiling it in thermos flask for a minute and then cooling it without shaking. 3) Now add some yeast to the glucose solution and fix two holded rubber stopper to the flask.

What is anaerobic GCSE PE?

Aerobic and anaerobic exercise Depending upon whether the body uses oxygen or not in order to perform physical activities determines if the activity is aerobic (with oxygen) or anaerobic (without oxygen).

What sports use aerobic respiration?

Examples of aerobic activities include marathon running, 5,000 metres, distance swimming, jogging back to reposition in football, dancing, canoeing and cross-country skiing.

What are the 4 steps of aerobic respiration?

Aerobic respiration is a series of enzyme-controlled reactions that release the energy stored up in carbohydrates and lipids during photosynthesis and make it available to living organisms. There are four stages: glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation.

What are the main steps in aerobic respiration?

Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain. Glycolysis: Glucose ( 6 carbon atoms) is split into 2 molecules of glyceraldehyde phosphate (3 carbon each), then these are turned into pyruvate (3 carbons each). This produces 2 ATP and 2 NADH.
