Mkey [24]

Answer:

Broad-spectrum antibiotics can cause antibiotic resistance.

Explanation:

  • Antibiotics are the substances that inhibit the growth of or kill the bacteria and hence, these are used as medications for the treatment of a lot of bacterial diseases.
  • These antibiotics can either be of broad-spectrum or the narrow spectrum.
  • The broad-spectrum antibiotics are the ones that are effective against a variety of bacteria, both gram-positive and negative whereas the narrow-spectrum antibiotics are the ones that target only a specific type of bacteria.
  • Since the bacteria can mutate very fast and hence, develop antibiotic resistance, the doctors usually avoid prescribing broad-spectrum antibiotics and only use them when the causal bacteria is completely unknown.
  • Hence, in the given case the provider prescribes separate medications for both types of bacteria.

1. Enzyme is the molecule that serves to make reactions work. Enzymes are biochemical catalysts that catalyses chemical reactions in a cell by acting on substrates and convert them to products. Their rate of action increases with increase in substrate concentration, reaching optimum when all active sites of the enzyme are engaged.

2. Plastid are the tiny sacs in the cell that may contain starch. Plastid are major cell organelles found in the cells of plants and algae. Plastids are site for the manufacture and storage of important  chemical compounds used by the cell. They often contain pigments used in photosynthesis, and the types of pigments present can change or determine cells color.

3. Lysosome are packets within the cell that contain digestive enzymes. Lysosomes are one of many organelles found in animal cells. they are tiny like sacs filled with enzymes that enables the cell to process nutrients. They contain digestive enzymes which helps in the digestion of worn out organelles, food particles and engulfed viruses or bacteria.

4. Mitochondrion is a structure within a cell that is responsible for production of energy. Energy in a cell is produced through a process of cellular respiration which involves use of nutrients with oxygen gas to yield energy inform of ATP, water and carbon dioxide. The process takes place in the mitochondrion where oxygen acts as proton acceptor in the electron transport chain coupled by production of energy.

5. An Organelle is a small structure that serves specialized functions. A cell is made up of various organelles that help it perform its functions. Each organelle is specialized to perform as specific function different from other organelles, for example ribosomes is an organelle involved in the manufacture of proteins.

6. Golgi apparatus are group of flattened sacs that package and export materials out of the cell. Golgi apparatus also called golgi complex or golgi body, is a membrane bound organelle in eukaryotic cells that is made up by a series of flattened, stacked pouches called cisternae. They are responsible for transporting, modifying, and packaging proteins and lipids into vesicles.

7. Vesicles are tiny sacs connected to the Endoplasmic reticulum and Golgi apparatus. Vesicles are small structures within a cell, or extracellular, consisting of fluid enclosed by a lipid bi-layer. they form naturally during the process of secretion (exocytosis), uptake (endocytosis) and transport of materials within the cytoplasm.

Compare and contrast aerobic respiration with photosynthesis in
Nataliya [291]

Answer:

Aerobic respiration;this is the process of breaking down of glucose  <u>with Oxygen</u> to generate energy  as ATPs in living cells

Location- Matrix  and inner membranes of mitochondria

Energy source_oxidative phosphorylation of glucose

Waste product-water( oxygen accept the final electron to form water)

.

38 ATPs from 1 glucose molecule

Explanation:

Photosynthesis; this is the process of reducing C02 with hydrogen ion, from water  i<u>n the presence of  sunlight , enzymes and green pigment chlorophyll</u> to form <u>glucose</u>

Location- stroma and thylakoid membranes of chloroplast

Energy source-photo-phosphorylation(sunlight)

Waste product-Oxygen

18ATPs
