Cellular Respiration

Light energy does not affect respiration, but it is needed for photosynthesis, which in plants creates the chemical compounds (carbohydrates) that are oxidized in cellular respiration.

The mitochondria is where two important steps, the Kreb's cycle and oxidative phosphorylation, of cellular respiration take place. This organelle is central in respiration and is often called "the powerhouse" of the cell.

Active transportation needs energy.(ATP). ATP is produced by mitochondria

Pyruvate is converted to ethanol in alcohol fermentation.It is converted to lactic acid in lactic acid fermentation.

Cellular respiration needs glucose. Glucose is produced by photosynthesis

This cannot be answered correctly. You will have to give me some choices to chooses from.

Mitochondria are the organelles where cellular respiration occurs.

When you breathe in oxygen you expel carbon dioxide, your bodies waste product. Your heart pumps blood from the right ventricle into the lungs where the CO2 (carbon dioxide) "jumps off" and the O2 (oxygen) "jumps on" the red blood cells. With the O2 being carried on little "handles" of the hemoglobin molecule of the red blood cells, it travels back into the heart from the lungs and is then pumped out into the body from the heart's left ventricle, through the aorta and into the body. The O2 is carried by the blood to every area and organ of the body, where it "nourishes" the cells. As the blood travels further from the heart and more waste builds, the CO2 content is higher than the O2 content and the CO2 waste is carried back to the heart by the blood, dumping its waste into the lungs and is then expelled in your breath. This gas exchange is made possible because of changes in pressure gradients.

i'm looling for the answer smartass ...... answers please .. for those normal people

Cellular respiration is the process by which energy is released from food molecules and stored in molecules of ATP, the energy currency of the cell. Without ATP cells could not function.

In sports, cellular respiration is the process through which our body converts glucose and oxygen into energy to fuel muscle contractions during exercise. This process produces ATP, the energy currency of cells. In science, cellular respiration is a fundamental metabolic process that occurs in all living organisms, breaking down organic molecules to release energy for cellular activities. It involves three main stages: glycolysis, the citric acid cycle, and oxidative phosphorylation.

There are more mitochondria in muscle cell than in most other cells in the body because the muscles do more movement. This means that the muscles need more energy.

they are they same. the products of photosynthesis are oxygen and glucose and the reactants of cellular respiration are gluose and oxygen.

The production of carbon dioxide (CO2) is directly related to the rate of cellular respiration in the body, as CO2 is a byproduct of this metabolic process. During cellular respiration, glucose is broken down to produce energy, and CO2 is generated during the conversion of pyruvate in the Krebs cycle. An increase in cellular respiration rate, such as during exercise, leads to higher energy demands and subsequently more CO2 production, which the body then needs to expel through breathing. Thus, monitoring CO2 levels can provide insight into metabolic activity and the efficiency of respiration.

A primary waste product of cellular respiration is carbon dioxide (CO2). It is produced during the breakdown of glucose for energy in cells. The body removes carbon dioxide through the respiratory system, where it is transported from the bloodstream to the lungs and exhaled. This process helps maintain the body's acid-base balance and prevents the buildup of CO2 in the tissues.

Oxygen is required as the last electron carrier for the electron transport chain, or ETC. The ETC is necessary to aerobically process NADH, FADH2, and the other energy carrying products of the citric acid cycle. If there is no oxygen, then it is inefficient for the body to run the CAC, thus only glycolysis is performed, and the produced NADH is processed by anaerobic means to free up more NAD+ for continued processing. However, the amount of energy generated by anaerobic means is far less than that produced by aerobic means.

Yes, some cells can have only one mitochondrion, though this is relatively uncommon. For instance, certain unicellular organisms, like some types of yeasts or bacteria, may contain a single mitochondrion, while specialized cells in multicellular organisms may also exhibit a very low number of mitochondria. However, most eukaryotic cells typically contain multiple mitochondria to meet their energy demands.

The four main steps of cellular respiration are glycolysis, the Krebs cycle (also known as the citric acid cycle), the electron transport chain, and oxidative phosphorylation. Glycolysis occurs in the cytoplasm and breaks down glucose into pyruvate, producing a small amount of ATP. The Krebs cycle takes place in the mitochondria and processes the pyruvate to generate electron carriers. Finally, the electron transport chain and oxidative phosphorylation produce the majority of ATP by transferring electrons and utilizing oxygen to form water.

Energy derived from cellular respiration originates primarily from the breakdown of glucose, which can be obtained from carbohydrates in the diet. Additionally, fats and proteins can also serve as alternative sources of energy when glucose is scarce. During cellular respiration, these macromolecules undergo a series of biochemical reactions, ultimately converting their stored energy into adenosine triphosphate (ATP), the energy currency of the cell. This process occurs in the mitochondria of eukaryotic cells, involving glycolysis, the citric acid cycle, and oxidative phosphorylation.

We just talked about O2 binding and releasing [4 O2's at a time] from haemoglobin molecules that transport oxygen through the blood. The poisonous nature of CO comes from the fact that while it readily binds to haemoglobin it will not disassociate! Carbon monoxide poisoning [lack of O2 supply] results.
