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.
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.
In cells using regulated secretion, proteins are synthesized and stored in secretory vesicles at the cell membrane until an outside signal leads to their release. Protein modification is the process by which some proteins from the rough ER are altered within the Golgi apparatus in order to be targeted to their final destinations.
Protein trafficking is used to describe the process of moving proteins from the rough ER, through the Golgi apparatus, where they are modified and packaged into vesicles. Photosynthesis is the means by which plants make use of chorophyll and light to produce energy.
This section covers the basic stages in the light reactions of the photo-synthetic electron transport chain. Photosynthesis allows plants to use the energy in light to produce molecular oxygen. Photosystem II is the complex where this action occurs.
Once translated, proteins are dispersed throughout the cellular environment. This section covers the transport of a protein into a specific organelle--the mitochondria. Gradients are used to create energy that can power biological cyles. ATP synthase is powered by a hydrogen gradient, located in the mitochondria.
This section covers the action of this specific gradient.Respiration is the process by which organisms burn food to produce energy. The starting material of cellular respiration is the sugar glucose, which has energy stored in its chemical initiativeblog.com can think of glucose as a kind of cellular piece of coal: chock-full of energy, but useless when you want to power a .
The overall reaction for cellular respiration: (does this reaction look familiar? Overall, it is the reverse reaction of photosynthesis, but chemically, the steps involved are very different.) Overall, it is the reverse reaction of photosynthesis, but chemically, the steps involved are very different.).
Cellular respiration is the process by which the chemical energy of "food" molecules is released and partially captured in the form of ATP. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most commonly used as an example to examine the reactions and.
B. Cellular Respiration. Ecosystems contain plants, animals, fungi and bacteria.
takes place in the cytoplasm and the TCA (Krebs) cycle and electron transport take place in the mitochondrial matrix. During glycolysis 6-carbon compounds (glucose) C.
