The process of glycolysis takes place in the ____ of the cells.
The process of glycolysis takes place in cytoplasm of the cells.
In germinating seeds fatty acid are degraded exclusively in the
In germinating seeds, fatty acids are degraded exclusively in the glyoxysomes.
Fermentation is anaerobic production of
Fermentation is referred to as the decompostion of organic compounds anaerobically by enzymes yielding alcohol, organic acids and gases etc.
Glycolysis occurs in
Glycolysis is the breakdown of glucose into 2-molecules of pyruvate. It occurs in cytoplasm of cell (cytosol) and is the common step in the both anaerobic cand aerobic respiration. It results in formation of total 4 ATPs directly and 10 indirectly.
Complex IV contains ___ and two copper centres.
Complex IV contains cytocrome a and a3 and two copper centers.
Life without air would be
In anaerobic respiration, oxygen is not used in the breakdown of respiratory substrate.
____ is not the end product of the respiration.
During the process of respiration, oxygen is utilized, and carbon dioxide, water and energy are released as products.
The NADH synthesized in glycolysis is transferred into the ____.
The NADH synthesized in glycolysis is transferred into the mitochondria and undergoes oxidative phosphorylation.
At a temperature above 35 C
The optimum temperature for photosynthesis is 10 - 25 C for C3 plants and 30-45 C for C4 plants
The pyruvic acid produced by the glycolysis is used in ____.
there are three different ways in which different cells use pyruvic acid produced by glycolysis ,these are lactic acid fermentation,alcoholic fermentation and aeribic respiration.
Hydrolytic enzymes which act on low pH are called as
Hydrolytic enzymes which act on low pH are called as hydrolases.
During respiration in yeast.
In yeast, during anaerobic respiration CO2, C2H5OH and energy are formed.
Number of carbons in pyruvic acid is
Number of carbons in pyruvic acid is 3. It is also called keto pyruvic acid. During glycolysis pyruvic formed by the oxidation of glucose.
The complete oxidation of pyruvate takes place in ____.
The complete oxidation of pyruvate takes place in the mitochondrial matrix.
Krebs cycle occurs in
The enzyme involved in krebs cycle are localized in the mitochondrial matrix
The ____ enzyme helps in the reduction of pyruvic acid to lactic acid when there is inadequate oxygen in muscle cells?
In muscle cells, during exercise, when oxygen is inadequate for cellular respiration pyruvic acid is reduced to lactic acid by lactate dehydrogenase.
Oxysomes are present on
Oxysomes are F0-F1 particles
The formation of Acetyl Co-A from pyruvic acid is the result of its
The formation of aceptyl Co A from pyruvic acid is the result of its oxidative decarboxylation
Which of the following statements is true
We know that all enyzmes are proteins, but all proteins are not enzymes. The enyzmes are proteins made up of one or more than one polypeotide chains.
Which of the following enzymes is absent in mitochondria
Hexokinase is a absent in the mitochondria since it is enzyme of glycolysis which occurs in cytoplasm.
In ____, glycolysis is the only process of respiration.
In anaerobic organisms, glycolysis is the only process of respiration.
Evoluation of Co2 is more than intake of oxygen when
Because in organic like formic acid, the number of O2 is more, so the outcome of CO2 is more
Which one of the following is first step of glycolysis?
Glucose 6-phosphate is glucose sugar phosphorylated on carbon 6. This compound is very common in cells as the vast majority of glucose entering a cell will become phosphorylated in this way. Because of its prominent position in cellular chemistry, glucose 6-phospate has many possible fates within the cell.
During aerobic respiration ____ is/are released.
During aerobic respiration oxygen is consumed and carbon dioxide is released.
Respiration differs from combustions in
It is the process of cellular oxidation, in which breakdown of food in the presence of oxygen to release in corbon dioxide and energy which is used in cellular activites.
The heterotroph that gets the food indirectly from the plants is ____.
All the animals are heterotrophic. Either they obtain food from plants directly (herbivores) or indirectly (carnivores). In the given options, except tiger all other animals are herbivores so they get their food directly from the plants whereas tiger is a carnivore , gets the food indirectly from the plants.
Apparatus to measure rate of respiration and RQ is
Respirometer is an instrument for measuring respiratory quotient as well as rate of respiration
____ elucidated the TCA cycle.
The TCA cycle is named as Krebs’ cycle after the scientist Hans Krebs who first elucidated it.
____ can be called as respiratory substrates.
Respiratory substrates are the compounds that are oxidized during the respiration process. Usually carbohydrates are oxidised to release energy. In some special conditions, proteins, fats and even organic acids can be used as respiratory substances to release energy.
