The enzymes that digest carbohydrates are very specific and can only digest specific glucose monomers of a Polysaccharides. For example our body can digest starch since its made up of α-glucose monomers (the difference of α-glucose and β-glucose is just on the location of the hydroxl group). However <span>Polysaccharides</span> like cellulose are indigestible because cellulose is made up of β-glucose and the enzyme which digests polysaccharides in humans (amylase) cannot detect β-glucose linkages.
- An object's kinetic energy depends on its mass and its speed.
- The faster something is moving and the heavier it is, the more work it can do.
- Kinetic energy increases as an object moves faster.
- If an objects speed is doubled > kinetic energy is quadrupled.
<em>If an object is not moving, it does not have kinetic energy. </em>
These preparations are called Vaccines. A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing micro-organism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins.
Alcohol
may positively affect the cardiovascular system of people over 50 years old by
reducing the risk of clot formation.
<span>Just like with the other body systems, excessive alcohol can have lethal
effects on the cardiovascular system. Chronic alcohol use can upsurge the
workload of the heart which can then lead to arrhythmia's or what is called an irregular
heart beat, inflammation of the heart muscle or myocarditis, weakening of the
heart muscle or cardiomyopathy, increased cholesterol, and even hypertension.
Other problems are prominent with blood clotting and an increased workload of
the heart that is linked to cirrhosis of the liver.</span>
