Therefore this substance needs to be removed from the body before it interferes with muscle contraction. Lactic acid is the limiting factor of this energy system. The acid is designed to build up and accumulate in the system. As exercise continues it diffuses through the blood and muscle tissues in the hope of impeding muscle contraction. This is what makes our working muscles stop because we feel an uncomfortable burning sensation in our muscles because the passageway of oxygen is being blocked by the lactic acid.
Exploring enzymes through Lactex. Problem: Does pH affect the results of Lactex? Independent Variable: pH value Dependent Variable: Glucose Control: Lactex enzyme Hypothesis: I think pH will cause the result of Lactex to change. Materials: · Soap (basic) · Antacid (basic) · Soda (acidic) · Vinegar (acidic) · pH test strips · eye dropper · Cow’s milk Experimental Design: 1. Set up plastic cups 2.
Lipids are insoluble within water, they have high energy content and can be metabolized to release calories, but they have many other uses as well. Lipids help to create lasting structures within an individual’s body; lipids are also electrical insulators and are needed Bile is secreted from the gall bladder into the digestive tract, and lipase is secreted for
Research suggests that creatine improves strength and performance in teenagers who were already in shape and highly-trained for their sport.

Compression is also be used for helping with severe cases of shin splints, ensuring that it does not get worse.

In this, stretching and exercising the leg muscles, the muscle will be able to increase endurance, and prevent of muscle fatigue, thus preventing
Results Sheet, Experiment 13 Brand of Vinegar used:________________ Acetic Acid % from bottle label_____________ | Initial NaOH Reading(estimate to 0.1 mL) | Final NaOH Reading(estimate to 0.1 mL) | Volume NaOH used(Final – Initial) | Trial 1 | 9.5 | 1.3 | 8.2 | Trial 2 | 9.6 | 1.4 | 8.2 | Trial 3 | 9.7 | 1.4 | 8.3 | Average Volume of NaOH used | 8.2 | Calculations: Normality of the acetic acid: .82 Mass of acetic acid: 49.2 % acetic acid (divide the grams, above, by the volume you used to get g/L): 4.92 Answer questions A-G in the lab manual: A. What is the average % acetic acid in your vinegar sample? Standard vinegar is 5% acetic acid. How does your result compare with the standard? The average was 4.92 which is pretty close comparably to the standard.
The nutrients are and help the body by :- Carbohydrates:- these are a source of energy as are fats and proteins they provide fibre that is good for maintaining children's bowels.
