Which of the following is NOT involved in photosynthesis or cellular respiration?
a
cytokinins
b
chlorophyll
c
carbon dioxide
d
water
Answer:
a
Explanation:
Cytokinins are not involved in photosynthesis or cellular respiration. They are plant hormones that help regulate cell division and growth. On the other hand, chlorophyll, carbon dioxide, and water are all involved in photosynthesis and/or cellular respiration. The correct option is A.
What are Cytokinins?Cytokinins are plant growth hormones that stimulate cell division and delay senescence. They play a role in plant growth and development, but they are not involved in photosynthesis or cellular respiration. On the other hand, chlorophyll, carbon dioxide, and water are all involved in photosynthesis.
Chlorophyll is a pigment that absorbs light energy and converts it into chemical energy, while carbon dioxide and water are used to make glucose and oxygen through the process of photosynthesis.
Cellular respiration is the process by which cells convert glucose and oxygen into energy. Both carbon dioxide and water are produced as byproducts of cellular respiration. Therefore, all the options except cytokinins are involved in either photosynthesis or cellular respiration.
Therefore, the correct option is A.

If green plant cells are incubated in the presence of CO2 molecules containing radioactive carbon atoms, the fate of the carbon atoms can be followed. In an experiment, radioactive CO2 was given for 1 minute to plant cells, and then the cells were examined after 1, 5, 10, 20, and 30 minutes. The following molecules were labeled with radioactive carbon at some point(s): glucose, glyceralde-hyde 3-phosphate, glycine (an amino acid), 3-phospho-glycerate, ribulose 1,5-bisphosphate, and sucrose.
Required:
List these molecules in the order in which they first become labeled.
Answer:
GlycineRibulose 1,5-bisphosphate3-phosphoglycerateGlyceraldehyde 3-phosphate.GlucoseSucroseExplanation:
The glycine, among other amino acids, helps to improve chlorophyll production and promotes the process of photosynthesis.
Calvin cycle
During the carbon fixation phase, a CO² molecule combinate with a ribulose 1,5-bisphosphate to form 6-carbonated molecules, which will divide into two 3-phosphoglycerate molecules.
During the reduction phase, NADPH donates its electrons to reduce 3-phosphoglycerate molecules, and turn them into glyceraldehyde 3-phosphate.
During the regeneration phase, a glyceraldehyde 3-phosphate molecule leaves the cycle and goes to the cytosol to form glucose. This step can be done when three CO² enter the cycle and produce six glyceraldehyde 3-phosphate molecules. One of them leaves the cycle to form glucose, while the other five are recycled.
Cytosol:
Once in the cytosol, glyceraldehyde 3-phosphate molecules are used to form glucose and fructose. These two molecules are the monosaccharides that form the sucrose.
Once sucrose is formed, it is transported from the photosynthetic tissues to different parts of the plant by the phloem.

In the morning, Jorge watched a cartoon about a sarcastic rabbit. Later, in his psychology class, he viewed
the image above and readily identified it as a rabbit instead of a duck. Which of the following best explains
this phenomenon?
Answer:
The correct answer is - priming.

Explanation:
Each of the following medical problems involves a malfunction of an organelle or other cell structure. In each case, identify the organelle or structure involved, and indicate whether it is likely to be underactive or overactive.
a. A girl inadvertently consumes cyanide and dies almost immediately because ATP production ceases.
b. A boy is diagnosed with neonatal adrenoleukodystrophy (NALD), which is characterized by an inability of his body to break down very-long-chain fatty acids.
c. A young man learns that he is infertile because his sperm are nonmotile.
d. A young child dies because her cells lack an enzyme that normally breaks down a membrane glycolipid that therefore accumulated in the membranes of her nervous system.
e. A young child is placed on a milk-free diet because the mucosal cells that line his small intestine do not secrete the enzyme necessary to hydrolyze lactose, the disaccharide present in milk.
Answer:
a. mitochondria, underactive
b. peroxisome, underactive
c. flagella, underactive
d. lysosome, underactive
e. Endoplasmic reticulum/Golgi apparatus/transport vesicles, underactive
Explanation:
Cyanide is a toxic compound that inhibits the Cytochrome c Oxidase I (COI) in mitochondria, which is an enzyme known to catalyze the final step in the mitochondrial electron transfer chain. Adrenoleukodystrophy is an X-linked genetic disease caused by a mutation in the ABCD1 gene (ATP-binding cassette, subfamily D, member 1). ABCD1 encodes the adrenoleukodystrophy protein (ALDP), which is involved in the transport of long-chain fatty acids into peroxisomes. Flagella are cellular structures composed of proteins (microtubules) specialized to carry the male's DNA to the egg cell, i.e., they are responsible for sperm motility. Lysosomal storage disorders (LSDs) represent a group of inherited diseases caused by mutations capable of altering lysosome functions. LSDs are especially associated with defective (abnormal) lysosomal enzymes that are unable to degrade macromolecules such as, in this case, a membrane glycolipid. Finally, lactase is an enzyme produced in small intestine cells. Within these cells, the signal sequence of the preprolactase precursor is cleaved in the endoplasmic reticulum (ER). Subsequently, the protein precursor travels to the Golgi complex for processing (i.e., glycosylation), thereby a mature enzyme (lactase) is generated.
