sensory receptor A specialized structure that responds to specific stimuli from an animal's external or internal environment; transmits the information of an environmental stimulus to the animal's nervous system by converting stimulus energy to the electrochemical energy of action potentials. sex-linked trait An inherited trait, such as color discrimination, determined by a gene located on a sex chromosome and that therefore shows a different pattern of inheritance in males and females

In this hypothesis, Mitchell proposed that H+ pumping generates what he called the proton motive force, a combination of the pH gradient across the inner mitochondrial membrane and the transmembrane electrical potential, which drives the ATP synthesis from ADP and Pi. Summary The transformation of the chemical energy of fuel molecules into useful energy is strictly regulated, and several factors control the use of glucose, fatty acids, and amino acids by the different cells

placental mammals One of three groups of mammals that carry their young in the mother's body for long periods during which the fetus is nourished by the placenta. During this time the atmosphere and oceans formed, life originated (or possibly "colonized" Earth), eukaryotes and simple animals evolved and by the end of the precambrian they began to accumulate hard preservable parts, the common occurrence of which marks the beginning of the Cambrian

Note: If you are concerned about consuming large quantities of unhealthy theatre popcorn, try carrying a small Himalayan rock salt plate and lick it during the movie. Left: The cell membrane has pulled away from the cell wall marking the onset of plasmolysis called "incipient plasmolysis." Right: The entire cell contents (protoplast) within the membrane has shrunk into a blob in the center of the cell

In 1856, a man named Bigo sought Pasteur's help because he was having problems at his distillery, which produced alcohol from sugar beetroot fermentation. In contrast, in the polluted containers, the ones containing lactic acid, he observed "much smaller cells than the yeast." Pasteur's finding showed that there are two types of fermentation: alcoholic and lactic acid

The electron transport system transfers protons from the inner compartment to the outer; as the protons flow back to the inner compartment, the energy of their movement is used to add phosphate to ADP, forming ATP. Water flows across the respiratory surface of the gill in one direction while blood flows in the other direction through the blood vessels on the other side of the surface

Because there are a number of enzymes and steps involved in forming porphyrin rings, there are a number of possible points in the process where genetic defects could occur. Out of many possible types of fermentation processes, two of the most common types are lactic acid fermentation and alcohol fermentation (other types of fermentation such as methanol fermentation and acetone fermentation also exist)
