Cellular Respiration

Cellular Respiration is the series of metabolic reactions that takes place in a cell that harvests chemical energy. The energy is converted from the stored chemical energy in molecules to the stored energy in ATP.

What happens doing the stage of cellular respiration?

glucose and water are changed to carbon dioxide,water, and ATP (energy)

What are the organelles that digest and dispose of worn out mitochondria and other organelles by a process called autophagy?

Autophagy, being the degradation of cytoplasmic components as well as other organelles, is generally done with the lysosomes. The lysosomes, contain enzymes (hydrolase and others)to digest these worn out, damaged, or infected parts, which keeps the cell healthy and clean. mTOR regulates this process (mammalian target of rapamycin). I don't know of any other organelles that are involved in this process but lysosomes do carry out a similar procedure to autophagy. It's called autolysis, and that is basically when the lysosome, excretes all of its digestive juices into the cell. It's like a self destruct and the entire cell is condemned to a digestive end. Don't worry, it only applies to damaged cells.

What is the roles of bacteria in nitrogen fixation?

what is the chemical equation for cellular respiration in words

What are the main redox reactions during cellular respiration?

Glucose loses electrons through oxidation while oxygen gains thoes electrons throught reduction.

Where do the products in cellular respiration go?

The products of cellular respiration are water and carbon dioxide. The carbon dioxide is taken away from the cell by the bloodstream and carried to the lungs, where it is expelled when you exhale. The water simply becomes part of the water in your body. The human body is mostly water anyway.

Why is 36 ATP molecules important to aerobic respiration?

First you have to know that respiration happens in 3 steps: glycolysis, Krebs cycle, and oxidative phosphorylation.

Glycolysis, through substrate-level phosphorylation, yields 4 ATP, but it uses up 2 ATP, giving a "profit" of 2 ATP.

The Krebs cycle also yields 2 ATP through substrate-level phosphorylation.

Oxidative phosphorylation occurs through the electron transport chain. This process yields about 34 ATP.

This gives us a total of about 38.

The total CAN be 36 depending on how much ATP is used by the shuttles that transport electrons from NADH in the cytosol. (The shuttle can use up 0-2 ATP)

What 2 reactants are required for cellular respiration?

There are no 2 specific reactants. Many reactants can 'produce' energy. Gasoline, methane, ethane, propane, butane, etc all burn with a variety of oxidizers (oxygen it self being only one of them) and release heat energy.

Which statement describes how photosynthesis and cellular respiration are interrelated?

The statement " All the products of Photosynthesis i.e Sugar, Oxygen are the reactants of Cellular Respiration , and all the products of Cellular Respiration i.e Carbon Dioxide are the reactants of Photosynthesis ." ,describes that the two most integral metabolic processes i.e Photosynthesis and cellular respiration are inter-related .

What role does diffusion play in cellular respiration?

well ask yourself what does diffusion mean and compare it to cellular respiration and photosynthesis

What is another name for cellular respiration?

Tissue respiration, or internal respiration.

you are probably looking for aerobic respiration

What monosaccharide enters the process of cellular respiration?

Glucose is a sugar that provides energy for cellular respiration.During cellular respiration, a process called glycolysis occurs, converting glucose to pyruvate. The process releases high energy compoounds and is used for many purposes including respiration.

What organelle sites a cellular respiration?

The mitochondrion, where ATP (adenosine triphosphate/energy) is synthesized from ADP (Adenosine Diphosphate) and one inorganic phosphate molecule.

Why those the heart have more mitochondria?

Energy is released in the Mitochondria through a process called respiration.Heart muscle requires a lot of energy to keep its muscles contracting and working all the time , so it's cells have a lot of mitochondria.

Mitochondria are also present in cells which carry out Active transport (like cells in the gut wall) as active transport also require energy from respiration.

What is the terminal electron acceptor in aerobic cellular respiration?

NAD+ is the first electron acceptor in cellular respiration (O2 is the final acceptor).

Is respiration faster than photosynthesis?

What organelle does photosynthesis and cellular respiration occur in?

Respiration occurs in two compartments - glycolysis in the cytoplasm and the TCA cycle and electron transport chain in the mitochondria. However, cells that are actively photosynthesising do not need to respire because ATP is synthesised in the chloroplast.

When was cellular respiration discovered?

There were several scientist who discovered cellular respiration. One is Han Krebs, who discovered cellular respiration on citric acid cycle. Another is Claude Bernard, who invented cellular respiration's medicinal attribute.

How is cellular respiration a benefit to plants?

Respiration benefits plants as it provides them with energy and nutrients, innit.

What does cellular respiration remove from the air?

Cellular respiration removes oxygen from the air and releases carbon dioxide as a waste product.

Can cellular respiration and fermentation be used to release energy?

No. Either cellular repsiration or fermentation can be used to release energy depending on the presence or absense of oxygen. When oxygen is present, it acts as the terminal electron acceptor in cellular repritation, followed by the release of energy When there is no oxygen present, other organic molecules (like lactic acid) accept the terninal electron and energy is generated

How can i compare and contrast cellular respiration and photosynthesis?

Right here, just visualize the circles: Photosynthesis: * Only in plants and some bacteria * Occurs in chloroplasts * Reactants: CO2, H2O & Light Energy * Products: O2 & Glucose Similarities: * Both involve O2, H2O, CO2, H2O, Glucose & energy * Both are REDOX reactions Respiration: * In both plants and animals * Occurs in the mitochondria * Reactants: O2 & Glucose * Products: CO2, H2O & Energy
