Which enzymes are involved in both photosynthesis and respiration?

Cytochrome oxididase This is essential for both respiration and photosynthesis. It is responsible for transferring electrons from cytochromes to oxygen, which allows them to be expelled as water. It is found in all organisms that require oxygen for survival, whether they obtain it through breathing or through photosynthesis.

Cytochrome P450 enzymes These are proteins that catalyze the oxidation of drugs and other chemicals. They are present in almost every organ of the body and are important for hormones metabolism and detoxification. Cytochrome P450 enzymes are also used by bacteria and fungi as a method of defense against antibiotics; these enzymes break down certain medications so that they cannot kill the bacteria that contain them.

Enzymes play an important role in the process of energy conversion during cellular respiration and photosynthesis. Enzymes are very specific proteins that increase the rate at which a reaction occurs by many orders of magnitude. Without enzymes, most chemical reactions would happen too slow to have any effect on a living organism. Enzymes are required for food digestion, blood clot formation, nerve signaling, and many other processes necessary for life.

What is the result of photosynthesis when glucose and oxygen are added?

Photosynthesis is the process through which plants transform carbon dioxide and water into sugars using light energy. When glucose (sugar created during photosynthesis) mixes with oxygen, it produces usable cellular energy. This energy is utilized to power growth and all cellular operations. Humans also use this energy to build a strong body and think clearly.

Carbon dioxide and water are the only two elements used in the synthesis of sugar. Oxygen is used as well for splitting water molecules, so more oxygen means more hydrogen atoms are available for sugar production. More hydrogen atoms available = more fuel for the plant. Glucose is stored within the plant's cells in small concentrations that can be converted back into energy as needed. Also stored are carbohydrates such as starch that can be used as an energy source for plants during times of need or drought. Fruits and vegetables contain high amounts of carbohydrates stored in this form.

During photosynthesis, plants take in carbon dioxide and water from the atmosphere and use the energy from sunlight to produce simple sugars such as glucose and fructose. These simple sugars are then used by plants as fuel for growth and maintenance of their bodies. Some of the produced energy is stored in the form of carbohydrate for later use when nutrients are low or there is no enough sunlight for photosynthesis to continue at its current rate.

The amount of sugar produced by plants is very important for humans to have access to enough food to eat.

How are photosynthesis and cellular respiration related, slader?

Photosynthesis harnesses solar energy by turning carbon dioxide and water into glucose and oxygen. Cellular respiration, on the other hand, is the mechanism through which glucose and oxygen are transformed into energy. These processes are very closely related because they both involve hydrogen atoms being removed or added to molecules.

Photosynthesis occurs in plants and algae while cellular respiration takes place in organisms such as bacteria and humans. However, both processes share many similarities including the use of electron transport chains within cells that generate a proton gradient across membranes which can be used by ATP synthase to make ATP from ADP. Also, photosynthetic organisms such as green plants use light energy to split water into oxygen and hydrogen protons while oxygenic photosynthesizers such as cyanobacteria use sunlight to split water directly without producing protons. Finally, plant mitochondria contain their own DNA (mtDNA) which is used to encode proteins that are necessary for mitochondrial function. Similarly, human mitochondria contain their own DNA (numtDNA) which is similar to mtDNA except it was acquired from the nuclear genome long ago after humans and other animals separated from fish.

Photosynthesis uses solar energy to create organic compounds from inorganic substances found in air, water, and soil nutrients.

What are the electron carriers in photosynthesis and cellular respiration?

During glycolysis and the citric acid cycle of cellular respiration, NAD accepts electrons and donates them to oxidative phosphorylation. The similarly related nicotinamide adenine dinucleotide phosphate (NADP) is created by photosynthesis's light reactions and consumed by the Calvin cycle. Both are used as donors of electrons for oxidation-reduction reactions within cells.

The electron carriers are also called cofactors because they help enzymes function properly. For example, iron-sulfur proteins such as rubisco act as cofactors for ribulose-bisphosphate carboxylase/oxygenase (rubisco), helping it bind its substrate, carbon dioxide, and releasing oxygen as a product. Other examples include heme proteins such as cytochromes which bind to redox active metals (such as copper or zinc) in order to transfer electrons through membranes.

There are two main classes of electron carriers: flavins and porphyrins. Flavins are red pigments found in bacteria and some plants that can accept electrons from other molecules and then give them up themselves. They usually require other proteins to transport them around the cell. Porphyrins are blue-black chemicals made by certain bacteria and plants that can accept electrons directly from other molecules and then give them up at different places in their structure. Like flavins, they usually need other proteins to move around the cell.
