Organelle

by microfossils traces, biomarkers, and more. Archaea at first seemed very similar to Bacteria, and many were categorized as such. Only later was the new domain Archaea suggested. Just like Eukaryotes, Archaea have a nucleus and membrane bound organelles in addition to which they also share many similar features and pathways with humans on the molecular level, such as the enzymes used in transcription and…

Photosynthesis is the process where energy from the sun gets converted into glucose for the plant to use as food. The energy from the sun gets trapped in the chloroplasts and together with carbon dioxide and water, it is turned into glucose and oxygen. The glucose eventually gets used as energy for the plant to live and the oxygen is a waste product that is released. The oxygen is used by humans during cellular respiration. Photosynthesis began over 2 billion years ago when an organism first…

activities inside the cell. Mitochondria are needing to give energy to the cell and tissue. The columnar and squamous epithelium cell are found in the lining of the oesophagus.The mitochondria and lysosomes is used in the digestion system as an organelle is that the lysosome act as an enzyme which helps to break down the food or any of the…

Sejaphala M.D. Student No. 62399543 Unique Number: 770819 Introductory Microbiology MIB2601 Assignment 02 Due Date: 13 April 2018 QUESTION 1 1. Bacteria is stained using a primary stain called crystal violet and then fixed with a mordant which in most cases is iodine. While some bacteria have the ability to retain the primary stain, others discolor when exposed to the acetone and alcohol (95%). Hence, the Gram stain divides bacteria into two groups- these bacteria are grouped…

A light microscope works like a telescope using glass lenses to reflect light, which magnifies images which are naked to the human eye such as cells and dust. The lens closest to your eye is called the eyepiece lens. This usually has a magnification of x10. Objective lenses are lenses of several different strengths which magnify the image. The stage is the place where the microscopic slide sits. This is held in place by the clips. The light source (can be a mirror or a bulb) projects light onto…

Active and passive transport move oxygen, water, and nutrients into cells and remove waste. Active transport requires a chemical energy because it moves from lower concentration to areas of higher concentration. It uses ATP to pump the molecules against the concentration, which requires cellular of solute. Passive transport moves from areas at a higher concentration to low concentrations, so it doesn’t require energy. Active transport takes place in the membranes of both the mitochondria and…

parts of cells that turn sugars, fats, and proteins that we eat into forms of energy that the body uses to live. Cells are the smallest things that can reproduce themselves. Within cells, there are smaller sub-compartments known as organelles. Mitochondria are organelles found in the cells of every…

Kanamycin acts by binding to the active site of the small s-ribosomal subunit, an important functioning part of the organelle. Kanamycin inhibits the synthesis of the protein by causing an increased amount of mistranslation. The other antibiotics used in the experiment are Tetracycle and Streptomycin, both which act in different methods than Kanamycin. An important factor…

Smooth E.R. are a series of interconnected tubes that connect from the nuclear envelope to the golgi apparatus, they send substances to the golgi apparatus, which then package and send them to other areas of the cell. Smooth E.R. also produce and metabolizes lipids, as well as producing steroid hormones, especially in the adrenal cortex and the endocrine glands. Smooth E.R. also play a large role in detoxifying organic chemicals, especially in the liver, converting them into substances that are…

Caulobacter Crescentus is a dimorphic, α-proteobacterium found in oligotrophic environments. Their dimorphic cell cycle produces two morphologically and functionally different daughter cells, known as the stalked cell and the swarmer cell. The stalked cell remains anchored to the substratum and is sessile, while the swarmer cell is motile. Upon chemotaxis, the swarmer cell disperses in search of nutrients. Once sufficient nutrients are located the cell cycle can continue. In the early phases of…
