What is the gaseous by-product of cellular respiration?
The gaseous by-product of cellular respiration is carbon dioxide (CO2). It is produced during the breakdown of glucose in the mitochondria of cells and is released into the bloodstream to be transported to the lungs and exhaled from the body.
Does glycolysis operate under aerobic or anaerobic conditions?
It isn't, it is a strictly anaerobic process. However it may occur in organisms that use oxygen in a related process.
How might photosynthesis and cellular respiration be considered inverse processes?
Photosynthesis is the process by which plants convert carbon dioxide and water into glucose and oxygen, using sunlight as an energy source. Cellular respiration, on the other hand, is the process by which organisms break down glucose and oxygen to produce energy, carbon dioxide, and water. These two processes are considered inverse because they involve the opposite chemical reactions - photosynthesis captures energy to build molecules, while cellular respiration releases energy by breaking down molecules.
How many peptide bonds are in a 151 amino acids?
150
Think of it this way: Amino acid ---- Amino acid
That's one bond for two monomers
Amino acid ---- Amino acid ---- Amino acid
That's two bonds for three monomers
Then you can say there are 150 bonds for 151 monomers.
What is monosaccharide glucose?
They are the simple sugars in a carbohydrate (ex. glucose) All carbohydrates, whether it be simple glucose or complex starch, are classified as a sugar. Any of a class of carbohydrates that can't be broken down into simple sugars by hydrolysis. A monosaccharide is the most basic unit of carbohydrates and the simplest form of sugars.
What sugars form to make lactose maltose and sucrose?
Sucrose is table sugar and is a member of the class of compounds known as carbohydrates. The name carbohydrate literally describes the composition of these chemicals. They are made of carbon and the components of water; hydrogen and oxygen. The chemical formula of sucrose is C12H22O11. Note the ratio of Hydrogen to Oxygen; H22O11 reduces to H2O.
Where are the the carriers of the electron transport chain located?
I don't think so. I think they are located in the inner membrane of the mitochondria, but I could be wrong.
Why do eggs and sperm only contain half the number of chromosomes?
Eggs and sperm each contain half the number of chromosomes to ensure that when they combine during fertilization, the resulting zygote will have the correct number of chromosomes. This process helps maintain genetic stability and prevents an overabundance of chromosomes in offspring.
What is the polymer for a nucleic acid?
DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are both polymers, with repeating units (monomers) of nucleotides, which are made up of:
- a nitrogenous base
- a 5-carbon sugar (deoxyribose or ribose)
- a phosphate group
Does nitrogen pollute the air?
Nitrogen is a normal component (about 80%) of the air you breathe. It is inert under most circumstances (excluding deep sea work where nitrogen narcosis or Rapture of the Deeps, might occur)
When there is too much nitrogen in the air, it is usually looked at as too little oxygen.
Though nitrogen is a naturally occurring in air, nitrogen oxide, which is mainly produced by road traffic. In excess it is known to give rise to acid rain. The main affect of NO2 in air is that it contributes to the formation of photochemical smog. It can also cause respiratory problems because it causes inflammation of the lining of the lungs and reduce immunity to lung infections
Which macromolecules are hydrophobic?
Carbohydrates are compounds made up of carbon, hydrogen, and oxygen atoms. contains monosaccharides (single sugar molecules). use it as main source or energy
Lipids are made up mostly from carbon and hydrogen atoms. some lipids are formed when a glycerol molecule combines with fatty acids.
Nucleic acids contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers assembled from individual monomers called nucleotides. they store and transmit hereditary information. the 2 kinds are RNA and DNA
Proteins contain nitrogen as well as carbon, hydrogen, and oxygen. they are polymers of molecules called amino acids.Some proteins control the rate of reactions and regulate cell proccesses . some are used to form bones and muscles. others transport substances into or out of cells or help fight disease
What makes up part of the Cell's membranes?
The main 'component' of the Cell's membranes are fatty acids, also known as lipids.
When does a Dna molecule replicate?
DNA replication occurs during the S phase of the cell cycle, just before cell division. This process ensures that each daughter cell receives an identical copy of the genetic information. Replication is a highly accurate process due to the complementary base pairing between the original DNA strand and the newly synthesized strand.
What do the 20 amino acids vary in?
The amino acids vary in the side groups, usually designated by "R" on the chemical structures for amino acids.
The invariant parts are the amino group (NH2-), central (-CH-) group, and the carboxyl (-COOH) group.
Connected to the central carbon on the (-CH-) group is a side group which is part that varies.
How did Antoine Lavoisier recognized hydrogen?
he, like found it in a suit case with like Zacharaist and stuff
What are the building blocks of DNA and RNA?
See related links and questions below.
What is the scientific name for a human cell?
The scienific name for cheek is Prezwaregalopigas or Stratified (stacked) Squamous (flat) Epithelium (external covering cells)
Which process converts oxygen and food into cellular energy?
That process is called as biological oxidation. Glucose is the best example of biological oxidation. Here the end products are same. They are water and carbon bi oxide. In the biological oxidation the energy is released in step wise fashion in multiple steps. In the chemical oxidation the energy is released in single step. The amount of energy is exactly same in both the processes. Chemical oxidation is like jumping from the top of the building. Biological oxidation is like coming down via steps. You come down at the same place. But you may end up in braking your legs in the process of jumping down. In biological oxidation, you do not end up in braking your legs.
Proteins have a wide variety of jobs. Some proteins are used in the maintenance of the cells structure. Proteins can be used to move various portions of the cell do different locations within the cell (eg chromosome movement during mitosis). Other proteins, found in cell membranes are used in the active and passive transport of molecules (eg. aquaporins, sodium channels). Many proteins are enzyme which catalyze reactions within the cell (eg. Hexokinase).
In short proteins (in general) do not have one specific job but different proteins have different functions.
Which has more energy ATP or AMP?
ATP.
You can think of the energy as being stored in the bonds between phosphate groups. ATP has the structure
adenine - ribose - phosphate - phosphate -phosphate
AMP is similar, but has only one phosphate group attached to ribose. So in ATP there are two high-energy bonds linking the extra two phosphate groups to AMP.
When ATP is split (hydrolyzed) in the cell, one of two things happens:
# Energy is released, a free phosphate group detaches, and ADP remains. # Energy is released, a free pyrophosphate group (P-P) detaches, and AMP remains. In this case the pyrophosphate may itself be split, releasing another packet of energy.
What is the characteristic property of water?
The characteristic property of water is its high polarity, which results in hydrogen bonding between water molecules. This gives water its unique properties such as high surface tension, cohesion, and ability to dissolve many substances.
What types of RNA are present in protein synthesis?
All forms of RNA are involved in protein synthesis: mRNA, rRNA, and tRNA.
Messenger RNA (mRNA) is the transcript with the codon sequences specifying which amino acids are needed and in what order. Transfer RNA (tRNA) binds to amino acids and brings them to the ribosome where the transcript is read and the protein assembled.
What happens to the introns and exons during transcription?
After transcription, the mRNA is processed by the spliceosome, which splices out the introns (because introns are not part of the coding sequences for protein), and "stitches" the exons together to form the final transcript that is sent to the ribosome for translation.
