In the presence of oxygen, glycolysis is followed by?

d, because the Krebs cycle is the next step in energy generation (when oxygen is present). (a) is incorrect, because lactic acid fermentation occurs when there is no oxygen. (b) is incorrect, because alcoholic fermentation is also anaerobic, and occurs mainly in yeast. (c) is incorrect, because photosynthesis does not require oxygen to occur.

respiration..\n\nco2 is given off, it goes through our blood stream, reabsorbed by the alveoli, switched out with o2 by respiration

The starting substances in respiration are a sugar (usually glucose) and oxygen.  The sugar first goes through glycolysis , which breaks it down into 2 pyruvates, 2 ATP, and  2 NADH. Then the 2 pyruvates go into the Krebs cycle (TCA cycle) and more NADH are made, plus 2 GTP.  Then all of the reducing power enters the electron transport chain where electron are transferred to oxygen to make H2O and ATP at the end of the respiration pathway.  The carbons in the glucose are converted into CO2.

generally glucose is the intial substrate in glycolysis .......

False. One glucose enters glycolysis. That glucose is then converted to 2 pyruvate which then go onto become Acetyl CoA to enter the Kreb cycle. The Kreb cycle then spins twice creating CO2, 2-ATP, and 6-NADH & 2 FADH. These protons are then sent to the electron transport chain to produce ATP.

lack of oxygen causes this

Glycolysis is the breakdown of glucose into 2 molecules of pyruvate.  It occurs in the cytosol of the cell.  There are 10 enzyme-catalyzed steps, in which 2 net molecules of ATP are produced.

when we take in the food during the process of respiration the glucose is broken down to pyruvic acid CH3COC0OH BY THE process of glycolysis , initially by taking oxygen by cytoplasm . when it gets more oxygen the pyruvic acid enters mitochondria and is converted to CO2 AND H20 . This cycle is called KREB's cyle . the synthesis of ATP molecule takes place in the F1 particle of mitochondria . \nthe equaton is \nC6H12O6+O2---->CH3C0COOH + O2--->CO2 + H20 \nthis process is called aerobic trespiration \nrespiration involves oxidation of food ....\nthus kreb cycle is aerobic respiration and increase in oxygen increases it !!!!!\nPLEASE VOTE IT AS THE BEST ANSWER IF YOU LIKE IT ..PLEASE......\nI THINK I HAVE ANSWERED YOUR MANY QUERIES

i assume "respiration" in your context refer to cellular respiration..\n\ncellular respiration in simple terms breaks down glucose and produce energy in forms of adenosine triphosphates.(ATPs). ATPs are the energy currency in the body and the breakdown of ATPs provide the energy needed for other metabolic processes, including digestion. Looking at it another way, digestion of complex nutrients like carbohydrates produces glucose, which is the respiratory substrate..\n\nDiffusion - oxygen required for aerobic respiration enters individual cells by diffusion. Waste products of aerobic respiration such as co2 leave the cells by diffusion into the bloodstream.  in general, diffusion is a passive process which does not require energy from ATPs, be it facilitated diffusion or simple diffusion, both are exergonic processes.\n\nthe circulatory system would carry the materials needed for aerobic respiration, eg oxygen and glucose to the individual cells, oxygen in form of oxyhaemoglobin in red blood cells. The circulatory system also carries the waste products, eg co2 away for excretion. \nThe circulatory system requires the pump, i.e. the heart to work, and the cardiac muscles require ATPs from respiration for contraction.\n\nhope u can see that they are all interrelated now..=)

all of those?\nalthough glucose ususally goes trough with active transfer

1. In fermentation, pyruvic acid molecules from the glycolysis cycle are turned into other chemical compounds, and a little bit of energy (only two ATP molecules per molecule of glucose – actually four are produced in glycolysis, but two are used up before it reaches this stage) is produced, IN THE ABSENCE OF OXYGEN!\n2. It takes place in the cytoplasm.\n3. all eukaryotes, to some degree\n4. wine, beer, cheese, medications...all are products of fermentation

This is called cellular respiration (there is also anerobic respiration, which takes place when there is no oxygen).\n\nAny search engine will give you tons of hits on these terms.\n\nGood luck!

Glycolysis is a process that breaks down glucose without the presence of oxygen. This process occurs in the cytoplasm and involves 10 reactions that convert glucose to 3 carbon pyruvate. The first stage is priming of glucose. Glucose is converted to glucose 6 phosphate using a molecule of ATP, a process called phosphorylation. Then the glucose 6 phosphate is converted into fructose 6 phosphate through the process of isomerization. This is further phosphorylated to fructose 1, 6 bisphosphate (phosphorylation). This fructose 1, 6 bisphosphate is cleaved into two molecules of glyceraldehyde 3 phosphate. The two G3P undergo substrate level phosphorylation, a sequence of 5 reactions, involving dehydrogenation where NAD+ is reduced, dephosphorylation where two molecule of ATP is formed, isomerization where the phosphate group moves, dehydration where the molecule lose water and dephosphorylation where 2 molecules of ATP are generated and two molecule of pyruvate is formed. \n\nThe fact that glycolysis produces ATP fulfills a minor energy requirement of the cell, since ATP is the energy currency required for cellular functions to work. Another minor energy requirement is the formation of NADH, because the proton in NADH is required to activate the proton pump at the electron transport chain, which, in turn, activates the enzyme ATP synthase responsible for the synthesis of many ATP molecules (aerobic respiration = with oxygen)\n\nThe major relation of glycolysis to the energy requirements of the cell is the transformation of glucose to pyruvate. Pyruvate is decarboxylated and attached to coenzyme-A to form acetyl-coA, which then goes through krebs cycle. Both these processes form NADH (and ATP in the case of the krebs cycle), which can then provide many protons to activate ATP synthase. (aerobic respiration = with oxygen)\n\nMoreover, pyruvate can also be used in the absence of oxygen through anaerobic respiration. Through this process, ATP can be formed without oxygen and can thus fulfill energy requirements of the cell.\n\nVery long but hope this helps =)
