Organelles
Which organelle is associated with being the 'Brain' of the cell?
What is the nucleus?
Responsible for delineating organelles and the cell itself.
What is a membrane?
An orderly step-wise progression of chemical reactions medicated by enzymes.
What is a biochemical pathway?
What is the pigment that is primarily responsible for the absorption of visible light at the beginning of photosynthesis?
What is Chlorophyll?
These are the five (5) stages of cell division in somatic cells.
What are G1, S, G2, Mitosis and Cytokinesis.
Which organelle is known as the 'Powerhouse' of the cell?
What is the mitochondrion?
Large quaternary proteins associated with the construction of proteins.
What is are ribosomes?
This pathway begins with a 6 carbon carbohydrate and ends with the formation of the 3-C compound pyruvic acid.
What is glycolysis?
Chlorophyll is not the only pigment in plants that absorb light in the photosynthetic process. These additional pigments also contribute to photosynthetic effeiciency.
What are accessory or antenna pigments?
This step distinguishes the difference between mitosis and meiosis at metaphase I in meiosis.
What is cytokinesis?
Which organelle contains the Thylacoid and Lamellae?
What is the Chloroplast?
Made of microtubles, a stator and a rotor these structures aid a cell's motility.
What is are flagella?
This biochemical pathway requires the activation energy of two ATP molecules and eventually yields a net gain of 2 ATP molecules.
What is glycolysis?
Photosystem I and Photosytem II must transport an electron to oxygen to form water and complete the biochemical reaction. Ps i and Ps II are not in direct contact so they rely on this molecule to transport the electron between them.
What is plastoquinone or the PQ molecule?
When it comes time to replicate DNA in the cell cycle this is the stage where that occurs.
What is the S phase?
Which organelle contains the Electron Transport System (ETS)?
What is the mitochondrion?
Seem to form out of endoplasmic reticulum to complete the job started by ribosomes and RNA.
What are Golgi bodies or Golgi Apparatus?
Upon crossing the outer mitochondrian membrane and the crista this 3-carbon compound is decarboxylated into carbon dioxide and joins with co-enzyme A to form this compound at the beginning of the Kreb's cycle.
What is Acetyl Co-A?
This molecule is identical in both respiration and photosynthesis. It's form and function in both depend on a build up of hydrogen ions to complete their tasks.
What is ATP synthase?
This number of cells formed at the end of the meiotic process distinguishes meiosis from mitosis. At the end stage they are no longer referred to as daughter cells but gametes.
What is 4?
This organelle is used in cell defense and autolysis.
What is the lysosome?
A packaging device for food, waste, enzymes...whatever the cell need to package or isolate.
What is a vesicle?
In \respiration there occurs the formation of ancillary compounds NADH2 and FADH2 whose primary function is to transport this ion and concentrate it within the cristae space in preparation for powering ATP Synthase.
What are hydrogen ions?
In order for oxidative phosphorylation to go to completion in the presence of oxygen the reaction requires the input of 2 ATP molecules but the resultant reactions are responsible for the production of this many total ATP molecules.
What is 40 ATP molecules by the end of oxygenated ETS?
Because of this phenomenon meiosis is also referred to as reduction division.
What is the process of halving the number of chromosomes in the gametes from the original number in the mother cell?
