Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Answer:
A
Explanation:
Radioactively labelled amino acids will be found in the ribosomes. These are the organelles that are the site of protein synthesis.
Amino acids are taken up into the cytoplasm from the surrounding cell culture medium. Amino acids are then bound to tRNAs (with the enzyme aminoacyl-tRNA synthetases) and taken to the ribosome, where they are assembled into a polypeptide chain by the translation machinery.
Answer:
d. K+ and Na+ both diffuse into the cell along their concentration gradients and drive the transport of glucose.
Explanation:
Na/K pump is a pump located on the plasma membrane which uses ATP to move 3 Na ions out the cell and brings in 2 K ions into the cell. It is an example of primary active transport. As a consequence,concentration of Na is higher outside the cell, while K concentration is higher inside the cell.
Glucose is transported in the cell against its gradient, together with Na ions (symport) which move down their concentration gradient.
This is an example of secondary active transport because it uses the energy from the primary active transport to move other substances such as glucose against their own gradients.
