E. Both B and C
Whiplike movement of the cilia on the surfaces of cells in the respiratory airways (trachea) and the fallopian tubes.
Ciliary movement
In the trachea, the cilia beats in a ___ motion toward the mouth to filter out substances together with secretions for the individual to either expectorate or swallow it.
forward
Movement of the entire cell in relation to its surroundings
Ameboid Locomotion
Jellylike matrix within the cell that contains intracellular fluid. A highly organized structure and complex lattice network where the organelles are situated in advantage and according to the metabolism of the cell.
Cytoplasm
The passageway of DNA and RNA to
communicate with other organelles of the cell
Nuclear pores
A circular structure that serves as sites of ribosome assembly. It contains clusters of protein, DNA, & RNA.
Nucleoli / nucleolus
The nucleus contains how many pairs of chromosomes?
23 pairs
46 chromosomes in total.
Contain a coding system for particular
chemicals to be produced in the body, such as neurotransmitters and hormones
Chromosomes
Commenced in 2002 to improve gene therapy and prevent the next generation in contracting those diseases because of their susceptibility.
The Human Genome Project
In this chromosome, the following diseases can be expressed: Lupus, emphysema, Alzheimer’s disease, leukemia
Chromosome 12
A process wherein the food that we ate must be processed and converted to ATP by the mitochondria. It is the conversion of these substrates into energy compounds so our body could use it.
Internal cellular respiration
Abundant in an area of high metabolism that needs a lot of energy
Mitochondria
More acidic than the cytoplasm and because of its high acidity, the cell can protect itself
Lysosomes
The entry point in a golgi apparatus
Cis cisterns
The exit point in a golgi apparatus
Trans cisterns
This organelle lacks ribosomes
Smooth / agranular endoplasmic reticulum
Programmed cell death. Once the cell has
achieved its purpose, it will suddenly die.
Apoptosis
Traumatic cell death, unprogrammed
cell death. An example is following a deep injury and the wound was infected, there’s no blood supply/circulation and it necrotizes.
Necrosis
A vacuole that ate unused hormones, chemicals, and excess products inside the cytoplasm is called (1)___, while a vacuole that ate itself is called (2)___.
- phagocytic vacuole
- autophagic vacuole
A reaction that builds up is called (1)___, while a reaction that cuts down is called (2)___.
- anabolic
- catabolic
Determine the corresponding descriptions of these organelles
- Contain enzymes that oxidize reactions and detoxify harmful substances in the liver & kidney
- Suicide bags, contain fragments of other cell structures that are products of digestion
- A spherical or oval structure that contains hereditary units
- Located near the nucleus, processes, sorts, packs & delivers proteins, lipids to the plasma membrane & forms lysosomes & secretory vesicles
- A sausage-shaped structures that are the power-generating units of the cell
- Granules that contain rRNA & other proteins and synthesizes hemoglobin
A. Nucleus
B.
Lysosomes
C. Ribosomes
D. Mitochondria
E. Peroxisomes
F. Golgi apparatus

This is where biological oxidation happens
Crista (plural: cristae)
In the citric acid cycle / Kreb’s cycle, ATP is produced via ___. This process uses oxygen in order to phosphorylate
(remove phosphate and add it to the
adenosine).
oxidative phosphorylation
Part of the mitochondria that provides raw materials such as carbohydrates, free fatty acids
Outer membrane
In the chromosomes, the loop is a complex formation of globular units. Within those beads, they are wrapped
around a strand which is the DNA. If the strings are unwounded, the globular
units are found to be smaller spheres which are called ___. These smaller spheres code for certain amino acids and characteristics of the body.
histones
Determine the corresponding descriptions of the forms of lysosomes
- Lysosome is already digesting; fused with foreign
materials - It contains only digestive enzymes. The lysosome has yet to digest / engulf anything.
- It contains undigested wastes
A. Primary lysosome
B. Secondary lysosome
C. Residual body
- B
- A
- C
Complex series of tubules in the cytoplasm that is the site for steroid synthesis, particularly hormones for secondary characteristics
(i.e., testosterone, estrogen, progesterone).
Smooth / agranular endoplasmic reticulum
A condition where its symptoms are pain on the right side of
the body under the ribs and jaundice. It is caused by damaged and overworked liver cells in detoxification.
Liver cirrhosis
Additional: Jaundice - liver produces carotene which is not
right
Determine the corresponding descriptions of the steps in protein synthesis in the ribosomes
- tRNA matches the codons with amino acids
- Double helix is unzipped and mRNA
comes in to decode what the DNA
has - amino acids will attach to the growing
chain of amino acids and will stop once a stop codon is detected (12 amino acid chain) - 1 tRNA (transfer RNA) that will attach
to the mRNA - as the mRNA finalizes the
coding, it will go out of the nuclear pore and go to the ER
