Enzymology‚ Catalytic Mechanism‚ Carbohydrate Metabolism‚ Adenosine Triphosphate Enzymes are proteins and their function is to act as catalysts to speed up certain chemical reactions in the cell that would be slower without them. This process occurs as steps in a cycle with separate reactions in each step. If there is a missing product the step in the cycle will be incomplete and the normal function of the organism cannot be accomplished causing negative effects on the organism. The biological

The way we observe and interact with our world happens through our nervous systems. It is how we learn about our surroundings and how we function within those surroundings. But what would happen if something was affecting our nervous systems in ways that could both help us and harm us? Truth be told‚ there is.

The most common allergy among infants and young children‚ cow milk allergies are prevalent among 2.5 percent of children younger than three. Although around 80 percent of children outgrow their allergy by the time they are sixteen‚ it still remains in many children and adults. Unfortunately for those people‚ milk makes up an ingredient in many popular foods and they are unable to enjoy the same experiences as their friends and family. Milk allergies are not to be confused with lactose intolerance

The activities of MDM2 are highly controlled by extracellular and intracellular stress signals.These signals include genotoxic stress signals‚ ribosomal stress‚ oncogenic activation‚ and psychological stress signals. They function through distinct signalling pathways to regulate the ability of MDM2 to bind with p53‚ MDM2 E3 ubiquitin ligase activity‚ and the cellular localization of MDM2. The ability of MDM2 to export p53 to cytoplasm is blocked by the phosphorylation of MDM2 at these two positions

Skeletal muscle is a voluntary and striated muscle that attaches to the skeleton to allow control over posture and movement. Each skeletal muscle consists of bundles of muscles fibers called fascicles. These fascicles are composed of many individual muscle fibers or muscle cells that can be up to several millimeters long. These muscle fibers are composed of myofibrils‚ which are organized into thick filaments‚ myosin‚ and thin filaments‚ actin. These filaments are organized into repeating structures

types. These are called exitatory neurotransmitters and inhibitory neurotransmitters. Exitatory neurotransmitters stimulate different parts of the brain. Three wellknown types of exitatory neurotransmitters are dopamine‚ norepinephrine‚ epinephrine. Inhibitory neurotransmitters calm the brain and create balance. Three different types of inhibitory neurotransmitters are serotonin‚ gaba and dopamine. Although dopamine was already mentioned as an exitatory neurotransmitter‚ it is special because
