Four groups of organic compounds found in living things are lipids, carbohydrates, proteins, and nucleic acids.
Answer:
B. An incoming charged tRNA binds to this site.
Explanation:
This is part of a process called TRANSLATION, in which mRNA is translated into proteins by the ribosomes, it comprises 3 stages: Initiation, Elongation, and Termination.
The A site is part of the ribosome, which has 1 binding site for mRNA and 3 binding sites for tRNA: A: Aminoacyl or acceptor site; P: Peptidyl; E: Exit, and it´s involved in ELONGATION, where it binds to the Aminoacyl tRNA (charged tRNA), that has the aminoacid that´s going to be added.
Answer:
"C" is the answer, Myosin would be able to bind to bind to the exposed binding sites on thin filaments but would not be able to detach
Explanation:
ATP is required for muscle contractions. muscle fatigue results in the decline of muscle force generated over time during metabolic fatigue there is depletion of required substrate such as ATP or glycogen as muscle is not able to generate energy to power contractions. accumulation of metabolites from this reaction other than lactic acid or reactive oxygen species can also induce fatigue by interfering with the release of Ca++ from the sarcoplasmic recticulum.
Petroleum Products
Petroleum and its products are mainly composed of carbon polymers (chains), as the backbone, with different structural and functional groups. Plastic, for example, is made of polypropylene and polybutylene which is mainly made of carbon atoms, whose monomers are linked in a chain to form polymers that make up the products.
Synthetic rubber on the other hand is made of copolymers of carbon and other addictives such as styrene. Synthetic fiber is made of nylon that is composed of a copolymer between carboxylic acid and amides.
