Answer:
1. Lactic fermentation is a minor process which occurs after glycolysis in anaerobic respiration. In it, an enzyme found in most every organism called lactate dehydrogenase catalyzes a reaction between the NADH produced from glycolysis with the pyruvate molecules to create the NAD+ necessary to begin glycolysis.
2.Anaerobic respiration happens in muscles during hard exercise. Glucose is not completely broken down, so less energy is released than during aerobic respiration. There is a build-up of lactic acid in the muscles during vigorous exercise. The lactic acid needs to be oxidised to carbon dioxide and water later.
3.the food is broken down with the use of oxygen, it is called aerobic respiration. If the breakdown occurs without the use of oxygen, the respiration is called anaerobic respiration.
4.The electron transport chain is the third and final step of cellular respiration. ... Toward the end of the electron transport chain, the hydrogen from the coenzymes meets the oxygen that the cell has consumed and reacts with it to form water. In this way, water is created as a byproduct of the metabolism reaction.
5.Anaerobic respiration in yeast
The yeast has to switch to using anaerobic respiration to ensure it can survive. Ethanol and carbon dioxide are produced. Yeast can also be used to produce bread. Yeast respires using glucose in the sugar that was added tothe dough.

Answer:
Lactate reacts with oxidized nicotinamide adenine dinucleotide (NAD+) to form pyruvate, reduced nicotinamide adenine dinucleotide (NADH), and a proton (H+).
During heavy exercise, expiratory flow limitation and prolonged expiratory time result in higher average positive intrathoracic pressures that reduce ventricular transmural pressure and act like a Valsalva, Decreasing the rate of ventricular filling during diastole and reducing stroke volume.
Water, because at the end of the mitochondrion electron transport chain — part of ATP synthesis through oxidative phosphorylation (a.k.a. cellular respiration) — two (energy-depleted) electrons combine with one oxygen ion and two hydrogen ions (protons), so forming water, which is transported by the blood.
Therefore, yeast is a single-celled fungus that uses cellular respiration, which converts glucose and oxygen into carbon dioxide. Fermentation is anaerobic respiration and happens without oxygen. Glucose is converted to two ATP, ethanol, and carbon dioxide. Yeast fermentation is used to make beer and wine.
Adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes. Adenosine triphosphate.
Nicotinamide adenine dinucleotide (NAD) a coenzyme and signaling molecule. No acute distress, on physical exam.
Hydrogen ion, strictly, the nucleus of a hydrogen atom separated from its accompanying electron. The hydrogen nucleus is made up of a particle carrying a unit positive electric charge, called a proton. The isolated hydrogen ion, represented by the symbol H+, is therefore customarily used to represent a proton.
