This overview of the various processes involved in Energy Consumption shows the important connections between the plant and animal worlds.
These interrelated events are crucial to the success of life on Earth. This animation provides a closer look at the eight reactions that make up this important pathway.
In the matrix of the mitochondrion, the Citric Acid Cycle uses Acetyl CoA molecules to produce energy through eight chemical reactions. This animation provides an overview of the pathway and its products. Glycolysis oxidizes one molecule of glucose into two molecules of pyruvate through a series of 10 enzymatic reactions.
This animation takes a closer look at those reactions and the enzymes that catalyze them. Glycolysis is a series of 10 reactions that converts sugars, like glucose, into 3-carbon molecules called pyruvate. This animation provides an overview of the energy consumed and produced by the pathway.
Meiosis is a type of cell division involved in sexual reproduction. It occurs in all plants and animals that reproduce by way of gametes or spores.
Mitosis is the process of dividing the duplicated DNA of a cell into two new nuclei. Here we look at the stages of mitosis, as well as how the cell finally splits to form two new cells.
The term respiration has two relatively distinct meanings in biology. First, respiration is the process by which an organism takes oxygen into its body and then releases carbon dioxide from its body.

Transcription of a gene can occur at varying rates. When a signal from outside the cell changes the rate of gene transcription, this is known as regulated transcription.
When insulin is released into the blood stream, a number of signal pathways are initiated. Here we look at the pathway responsible for increasing the uptake of blood glucose. Certain proteins need to be kept available for quick mobilization when a specific signal is recieved.
In this example we see how proteins that allow glucose into a cell are recycled. During constitutive secretion, proteins are synthesized and moved to the cell membrane without regard to extracellular signals.LabBench Activity Dissolved Oxygen and Aquatic Primary Productivity.
by Theresa Knapp Holtzclaw. Introduction.
In an aquatic environment, oxygen must be dissolved in order to . Pearson Prentice Hall and our other respected imprints provide educational materials, technologies, assessments and related services across the secondary curriculum. Maybe you made the connection that 'aero' sounds like air and therefore must have something to do with oxygen.
Aerobic cellular respiration is a process that requires oxygen to convert food into ATP. The term respiration has two relatively distinct meanings in biology. First, respiration is the process by which an organism takes oxygen into its body and then releases carbon dioxide from its body.
Essay # 1. Habitat and Habits Frogs: Rana tigrina is the most widely distributed species in Northern India. Generally frogs are found in ponds, tanks, pools, ditches, etc.
Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of Oxygen. Strictly speaking aerobic means in air, but it is the Oxygen in the air which is necessary for aerobic respiration.
