What is the definition of Metabolism?
- Sum of chemical reactions that take place in the cell to provide energy.
What does DNA and RNA stand for?
Deoxyribonucleic Acid
Ribonucleic Acid
Which are the stages/steps of the Cell Cycle?
Interphase, Mitosis and Cytokinesis.
What is homeostasis?
Keeping internal conditions in balance or stable.
Which organelle are proteins created in and which RNA is mainly used in the addition of amino acids to the chain?
Ribosomes and tRNA
What is Anabolism and Catabolism? And how are they related.
Catabolism: The creation of smaller molecules from a bigger molecule and the releasing of energy.
Anabolism: Creation of bigger molecules from smaller molecules, using the energy from Catabolism.
Relationship: the energy from Catabolism is used in Anabolism.
Name the 5 nitrogenous bases.
Adenine, Guanine, Cytosine, Thymine and Uracil (Only in RNA)
Which are the Stages of Mitosis?
- Prophase, Metaphase, Anaphase and Telophase.
It is the ability of living things to recondition themselves to environmental factors.
Adaptation
Which lipid is the precursor of Steroids hormones and is the most common steroid in humans?
Cholesterol.
What does ATP stands for and how is energy released?
Adenosine triphosphate.
Breaking the covalent bond from the thrid and second phosphate group.
What is a nucleotide?
Nucleotides is made of:
- A phosphate group
- A sugar (deoxyribose, ribose)
- One of four nitrogenous bases
Define Crossing over.
- Process during which chromosomal segments are exchanged between homologous
What is the definition of Biology?
Study of living things or making questions about how living things interact in the environment.
Which is the classifications of carbohydrates and give and example of each
- Simple: Monosaccharides - Glucose, Fructose and Galactose // Disaccharides - Maltose, Lactose, Sucarose
- Complex: Polysaccharides - Starches, Fibers, Glycogen
Which are the two phases of Cellular Respiration?
- Phase One: Glycolisis
- Phase Two: Aerobic Respiration
Where is DNA located in eukaryotic and prokaryotic cells?
DNA is located in Nucleus, Mitochondria and Chloroplasts of Eukaryotic Cells in a double helix form.
In Prokaryotic Cells is found in the Cytoplasm.
Which stage of Interphase does certain cells, such as nerve and muscle cells, exit in?
G1
Enlist the 8 Characteristics of living things
Made of One or More Cells, Displays Organization, Grows and Develops, Reproduces, Respond to Stimuli, Requires Energy, Maintains Homeostasis, Adaptations evolve over time.
By which two processes are proteins broken down into monomers or grouped together to form polymers and explain them
Hydrolysis: A bond is broken, by addition of a water molecule. A molecule composed is split into two.
-Bigger into smaller
Dehydration: One monomer forms a covalent bond to another monomer, releasing a water molecule.
- Smaller into bigger
How are the two phases of Photosynthesis named?
- Phase One: Light Reactions
- Phase Two: Light-independent Reactions
Name and explain the functions of the 3 types of RNA.
mRNA (Messenger):
Copies the information of DNA.
Takes the information from DNA in a code form from the nucleus to the ribosome.
tRNA (Transfer)
Organizes the union of aminoacids according to the information of the DNA.
Transports aminoacids from the cytoplasm to the ribosomes.
rRNA (Ribosomal)
In charge of protein synthesis.
Proteins that are needed by the cell and creation of ribosomes.
Explain Mitosis and Meiosis.
