Answer:
The characteristics of allosteric enzymes are listed below.
Explanation:
1 They may have binding sites for regulatory molecules that are separate from the active site.
2 They tend to have sigmoidal curve of V0 vs [S].
3 They undergo conformational change as a result of modulator binding
Answer:
because the body requires a higher supply of oxygen
Explanation:
Cellular respiration can be divided into two different metabolic processes: aerobic respiration which needs oxygen (O2) and anaerobic respiration (without O2). The aerobic cellular respiration is produced when glucose molecules react with O2 in order to form ATP, the energy currency of the cell. Aerobic cellular respiration is the main source for generating ATP. During exercise, the requirement of O2 will be higher because the cellular respiration rate is increased in order to produce more energy (ATP). In consequence, during physical activities, it is required have to breathe faster to supply this O2, which enters into the lungs to be transported to all the cells through blood circulation.
The given question is incorrect. The correct question is:
Question: The thoracic cavity contains the ________. it is found ________ to the vertebral cavity.
a) digestive viscera: inferior
b) kidneys and spleen: deep
c) stomach and liver: superficial
d) heart and lungs: anterior
Answer:
d) heart and lungs: anterior
Explanation:
The thoracic cavity is one of the major body cavities. The thoracic cavity is also called the chest cavity. It is formed by the ribs, the chest muscles, the sternum (breastbone), and the thoracic portion of the vertebral column. It is present in the anterior to the cavity formed by the spine to house the spinal cord. The pericardial cavity is the fluid-filled space of the thoracic cavity present around the heart. The thoracic cavity also has two pleural cavities to house the lungs.
Radiation is responsible for the greatest loss of energy.
