Answer:
d
Explanation:
as a result of accumulation of waste products in the body , these substances are removed from the body via the skin hence they undergo cellular respiration
<span>The smallest unit that can evolve is a _____. cell</span>
Answer:
b. False
Explanation:
All living organisms such as plants and animals require energy to function properly (life activities). Thus, the organelle where energy from nutrients is released is generally referred to as mitochondria. Animals retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). These intermediary products are produced at the glycolysis and citric acid cycle stage.
Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Hence, during respiration, most ATP is formed as a direct result of the net movement of protons down a concentration gradient but not potassium against a concentration gradient potassium.
Answer:
Novobiocin target DNA GYRASE of gram positive bacteria.
Explanation:
Novobiocin is a bacteriostatic(slow down bacteria growth) or bactericidal i.e it kills bacteria , narrow spectrum antibiotics that target DNA GYRASE of gram positive bacteria. It acts by inhibiting the bacteria DNA gyrase hydrolysis thereby by interfering with the metabolic activities of bacteria. It is also a weak catalytic inhibitor of mammalian. Novobiocin inhibit DNA gyrase and topoIV by binding to the ATP pocket of GyrB and ParE, respectively.The Streptomyces strain that produces Novobiocin and it is more effective on gram positive bacteria that gram negative bacteria because gram negative bacteria are resistant to it.
