What molecules are often made of oxygen hydrogen and carbon only?
What molecules are often made of oxygen hydrogen and carbon only?
Carbohydrates. Carbohydrates are organic compounds that contain only carbon, hydrogen, and oxygen. They are the most common of the four major types of organic compounds. There are thousands of different carbohydrates, but they all consist of one or more smaller units called monosaccharides.
What organic molecules contain both amino and carboxyl group?
Proteins are polymers made up of nitrogen-containing monomers called amino acids. An amino acid is a molecule composed of an amino group and a carboxyl group, together with a variable side chain.
What are the two cellular processes?
The two cellular processes illustrated by the test tubes are cellular respiration and photosynthesis. During cellular respiration, the reactants—glucose (sugar) and oxygen—combine together to form new products: carbon dioxide molecules and water molecules.
What are the three cellular processes?
Cell Functions and Processes
- Osmosis.
- Cellular Energy Production.
- Cell Transport.
- Homeostasis.
- Anaerobic Respiration.
- Aerobic Respiration.
- Cell Diffusion.
- Photosynthesis.
What is the cellular process?
cellular process Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level.
What are the 3 main types of cellular work?
Your cells perform three main types of work: chemical work, mechanical work, and transport work (Figure 7-10). An example of chemical work is building large molecules such as proteins. ATP provides the energy for the dehydration synthesis reaction that links amino acids together.
What cellular process is affected by HPV?
HPV infects dividing basal epithelial cells where its dsDNA episomal genome enters the nuclei. Upon basal cell division, an infected daughter cell begins the process of keratinocyte differentiation that triggers a tightly orchestrated pattern of viral gene expression to accomplish a productive infection.
At what level does Multicellularity emerge?
The first evidence of multicellularity is from cyanobacteria-like organisms that lived 3–3.5 billion years ago.
