enzyme activity in skeletal muscle‚ particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ------------ Lactate + NAD The reaction above can move in both directions‚ forward (favored by Type II skeletal muscle) and reverse (favored by Type I skeletal muscle and the heart).

The Human Skeletal System Introduction The human skeletal system is comprised of both fused and individual bones; supported and supplemented by ligaments‚ tendons‚ muscles and cartilage. The skeletons purpose is to protect and support the delicate internal organs and provide a framework that allows the body to stand upright and move. It also produces blood cells and stores minerals that our body needs to function effectively. The skeletal system is a very important part of the human body. Without

Lesson 36 Assignments Biology Muscles and the Skeleton Provide Action and Support Every movement you make or every step you take is controlled by the systems of muscles and skeleton that moves and supports the body. The human boy is a complex and elegant mechanism influenced my many factors. Both muscles and the skeleton are not only good for movement‚ they also influence crucial functions inside the body and the skeleton provides support in maintaining the body’s shape and it protects internal

Frogs Dissection: 1. Where is the frog’s heart compared to its lungs? How do the locations of these two organs affect interactions between the frog’s respiratory and circulatory systems? The frog’s heart is in front and above the liver while the lungs are under the liver and off to the sides. The locations of these two organs affect interactions between the frogs’s respiratory and circulatory systems because a frog’s heart needs oxygen which is required from the lungs therefore the circulatory
