Thefood chainalso shows us how energy flows through the ecosystem. Since energy cannot be created or destroyed, it is transferred from organism to organism within an ecosystem by feeding. In our freshwater lake example, the aquatic plants used energy from the sun to create food through photosynth...
Another critical factor in the design of bioenergetics experiments is the choice of normalization factor(s). Metabolic flux through a given pathway will depend on the amount/activity of the enzymes and metabolic intermediates present in the sample, neither of which necessarily scales with other variab...
1). Additionally, we also demonstrated photosynthesis of bacteriorhodopsin or a membrane portion of ATP synthase, which is the original component of the artificial organelle. Our artificial cell system enables the self-constitution of its own parts within a structure of positive feedback loop. Fig....
Protein synthesis involves linking amino acids into a polypeptide chain in the order specified by the nucleotide sequence of a mRNA transcript. A simplified diagram of protein synthesis is provided in Fig.1a. The ribosome, a macromolecular complex composed of ribosomal RNA (rRNA) and many ribosomal...
This idea is intellectually very appealing, as mitochondria are also the only organelle in animal cells that posses their own DNA, mtDNA, which is localized in the physical proximity to the mitochondrial respiratory chain (MRC). Over the years, substantial evidence has emerged from morphological, ...
of the thylakoid membrane (ΔpH), and by the electrical potential difference (ΔΨ) between both sides that is created by the directional charge separations in PSI and PSII (Lyu and Lazár2017), because both processes create positive charges near the lumen (pside) and negative charges near ...
Which type of fermentation occurs in muscle cells when oxygen is no longer present? Lactic Acid Fermentation What do yeast produce during alcoholic fermentation that makes bread rise? Carbon Dioxide How many molecules of ATP are created during the fermentation of one glucose molecule> ...
An organelle that is the site of photosynthesis; it has chlorophyll in it and produces glucose. Vocab: light reactions The first part of photosynthesis where NADPH is created. Vocab: Glycolysis Glycolysis breaks down glucose molecules into pyruvates. Vocab: Products The result of a reaction/process...
Does catabolism include cellular respiration in its definition? Are electricity, food, heat, and light all forms of energy? What are the different uses of carbohydrates in the body? How are carbohydrates processed in digestion? What happens to activation energy when a ...
Where in the cell is the ATP produced? How does ATP and ADP balance catabolic and anabolic reactions? Is glucose a part of adenosine triphosphate? In terms of energy, what is the difference between glucose and ATP? What organelle produces ATP? Which part of ...
