B) The enzymes of glycolysis are located in the cytosol of the cell.
C) Glycolysis can operate in the complete absence of O2.
D) The end products of glycolysis are CO2 and H20.
E) Glycolysis makes ATP exclusively through substrate-level phosphorylation.
Answer:
D
Explanation:
The end product of glycolysis is pyruvate. This process occurs in the cytosol of the cell in the absence of oxygen and has a net ATP production of 2 and 2 NADH. When there is no oxygen, the pyruvate is converted to lactic acid. When there is oxygen , the pyruvate is channeled to the Krebs cycle in the mitochondria where it is used to produce more ATP. The formation of ATP in glycolysis is powered by the energy in the bonds of the molecules (substrate-level phosphorylation). This is unlike in Krebs cycle where most of ATP are formed through oxidative phosphorylation. The end products of Krebs cycle is CO₂ and H₂O.
All of the following statements about glycolysis are true except the one that states- The end products of glycolysis are CO2 and H2O. So the correct option is option D.
The glycolysis process can take place when there is oxygen present (aerobic) or when there is no oxygen present (anaerobic). Pyruvate is transformed into lactic acid in anaerobic conditions. The fact that glycolysis occurs widely in other species suggests that it is an old metabolic pathway.
Glycolysis in most cells takes place in the cellular cytosol. The process of glycolysis can be divided into two stages: the investment stage, in which ATP is initially consumed, and the yield stage, in which more ATP is eventually produced.

Explanation:
OA. A whale is a mammal that does not live on land.
B. A fish is not a mammal and does not live on land.
OC. A horse is a mammal that lives on land.
D. A snake is not a mammal but lives on land.
Whales are marine mammals that do not live on land, disproving the conjecture that all mammals live on land.
The correct counterexample that shows the conjecture “All mammals live on land” is false is option A. A whale is a mammal that does not live on land. Whales are marine mammals and live in water their entire lives. This counterexample disproves the conjecture that all mammals live on land.
Answer:
The correct answer would be mitochondria or chloroplast.
Endosymbiosis refers to the evolution theory which explains the origin of eukaryotic cells from prokaryotic cells.
It is believed that cell organelles like chloroplast, mitochondria et cetera were free-living early prokaryotic cells which were taken inside the other cells by the process of endosymbiosis. It led to the origin of eukaryotic cells which were able to perform photosynthesis.
Thus, Keiko should mark chloroplast or mitochondria in the diagram.
Answer:
mitochondria, chloroplast
Explanation:
Pedigree charts are used to trace the passing out of traits(characteristics) through generations.
In the given pedigree of 5 generations, the pattern of inheritance of genetic abnormality of polydactyly(extra fingers in hands and toes) is studied . The types of pattern of inheritance in traits over generations.
(a) Genotype of the parents for the trait Polydactyly in generation 1
Since each parent provide one allele of each trait to the offspring there are dominant and recessive genes on the basis of the expression of the character or trait. The genotype of the parents for thre trait of polydactyly in generation 1 is Recessive. Because both the parents do not have the abnormality and their offspring shows(expresses) the trait.
(b) In humans there are 46 chromosomes arranged as 23 sets of 2 chromosomes in a cell which is described as (2n). These somatic cells undergo Mitotic division to produce 2 identical daughter cell with 2n chromosomes and they are called diploid cells. When Meiosis takes place one cell is divide into 4 Haploid cells with 23 chromosomes each, ie, the single set of chromosomes represented by n. These Haploid cells are the gamates which transfer the genetic information from parents to offspring. The gamates are 2 types the sperm and egg cells , both are haploid and during fertilization a sperm cell fuses with eggcell to form a zygote with 2n (46) chromosomes.
