Answer
Difference between Glycolysis and Krebs' cycle
| Glycolysis | Krebs' Cycle |
| 1. It is found in the cytoplasm. It does not require O₂. | 1. Occurs in the matrix of mitochondria. It requires $O _2$. |
| 2. This process takes place in aerobic and anaerobic respiration. | 2. Occurs only in aerobic respiration. |
| 3. Its product is pyruvic acid. | 3. Contains $CO _2$ and $H _2 O$. |
| 4. It uses 2 ATP molecules, net gain of 2 ATP and 2 NADH are obtained. | 4. 30 ATP molecules are formed. 6 ATP are formed from 2 NADH obtained from glycolysis and a total of 36 ATP are formed. |

What are the reasons that you can think of for the arthropods to constitute the largest group of the animal kingdom?
Write any four differences between sympathetic and parasympathetic nervous system. Make a labelled diagram showing the nerve endings and synapses.
The morphology of the mycelium, mode of spore formation, and fruiting bodies form the basis for the division of the fungi kingdom into various classes which include four sub-division Phycomycetes, ascomycetes, basidiomycetes, Deuteromycetes. Members of Phycomycetes are found in aquatic habitats and on decaying wood in moist and damp places or as obligate parasites on plants, ascomycetes are mostly multicellular. The asexual spores are conidia produced exogenously on the special mycelium called conidiophores. Basidiomycetes are mushrooms, bracket fungi or puffballs. They grow in soil, on logs and tree stumps and in living plant bodies as parasites. The basidiospores are exogenously produced on the basidium.
i. Observed given table of Classification of Fungi and identify the class of fungi in which asexual spores are not found, vegetative reproduction occurs by fragmentation, and sexual organs are absent. (1)

Structures of the bacterial ribosome have provided a framework for understanding universal mechanisms of protein synthesis. However, the eukaryotic ribosome is much larger than it is in bacteria, and its activity is fundamentally different in many key ways. All ribosomes are composed of two subunits, both of which are built from RNA and protein. Bacterial ribosomes, for example of Escherichia coli, contain a small subunit (SSU) composed of one 16S ribosomal RNA (rRNA) and 21 ribosomal proteins (r-proteins) and a large subunit (LSU) containing 5S and 23S rRNAs and 33 rproteins. In contrast to their bacterial counterparts, eukaryotic ribosomes are much larger and more complex, containing additional rRNA in the form of so-called expansion segments (ES) as well as many additional r-proteins and r-protein extensions.
