Tutoring Biology 12, digestion is covered. The tutor mentions the products of fat digestion. Dietary fat is finally digested into glycerol and fatty acids, which can enter the absorptive cells of the small intestine. Source: Mader, Sylvia S. Inquiry into …
Tutoring biology, non-competitive inhibition may be mentioned. The tutor explains it. In yesterday’s post I explain competitive inhibition. Non-competitive inhibition is similiar to competitive inhibition in that it hinders enzyme function. The difference is that, with non-competitive inhibition, the inhibitor …
Tutoring biology, you might be asked about competitive inhibition. The tutor explains it. In my November 25, 2013 post, I explain what an enzyme is. Simply put, an enzyme is a biological catalyst that the body uses to speed up …
The tutor gives a few facts about glycolysis. Glycolysis happens in the cytoplasm of the cell. It takes a glucose molecule (C6H12O6) and reacts it to two pyruvic acid (C3H4O3) molecules. The process involves inputs and outputs of water and …

The tutor shares a fact that surprises him. Winter here is fairly mild; I think the mean daily temp in Jan might be around 5 deg Celsius, with the mean nightly low being around -1 deg Celsius. That being said, …
Tutoring biology 12, you cover the circulatory system. The tutor mentions a specific issue about it. The number one reason for the circulatory system is transport of oxygen to the cells and carbon dioxide away from them. This is done …
Biology: oxygen and carbon dioxide transfer through the blood Read more »
Tutoring Biology 12, you cover this concept. The tutor approaches it from a simple, practical point of view. You normally hear about monomers and polymers in organic chemistry. Think of the name polyester: it’s a polymer of esters. The esters, …
When you tutor biology, molecular movement and transport are topics you need to explain. Front and centre is diffusion. Diffusion is the tendency of particles to move from an area of high concentration to lower concentration. It happens spontaneously, meaning …
Tutoring Biology 12, you cover the cardiovascular system. The biology tutor discusses the gas exchange aspect. People commonly associate respiration with breathing. However, from a biology point of view, the meanings are different. Breathing is the physical process of bringing …
Tutoring Biology 12, you realize that with most organ systems, the hormonal control is the most difficult to retain. The Biology tutor continues about urine regulation with this discussion of aldosterone. Of course, urine is produced by the kidneys. If …
