Last one I'm not 100% sure.
Answer:
a. PGA down, RuBP up
Explanation:
RuBP, also known as Ribulose-1,5-bisphosphate is a molecule that assist in he fixation of carbon dioxide in the Calvin Cycle or light independent reaction of photosynthesis.
RuBP is combined with carbon dioxide using the enzyme known as rubisco to form an short-lived intermediate product which divides to form two 3-carbon molecule structure known as 3-phosphoglycerate.
<em>If the concentration of carbon dioxide is suddenly reduced, it thus means that the rate of production of 3-phosphoglycerate will reduce as carbon dioxide becomes a limiting factor. Hence, 3-phosphoglycerate's concentration will reduce while more RuBP will become available as a result.</em>
The correct option is a.
Answer:
They release chemical messengers to communicate with cells they may or may not be in direct contact with.
Explanation:
Unicellular organisms such as bacteria or yeast, 'talk' to each other through the release of chemicals. In bacteria, this is known as quorum sensing which allows them to determine the surrounding bacterial population density. In yeast, one of the more popular pathways is known as the mating factor pathway, which allow the organisms to find mates. Whereas, in multicellular organisms (such as humans), this chemical release allows for cell-cell co-ordination which keeps the system functioning correctly.
It is part of the cell theory
Explanation:
Below is a list of organelles that are commonly found in eukaryotic cells.
Organelle: Function
Nucleus: The “brains” of the cell, the nucleus directs cell activities and contains genetic material called chromosomes made of DNA.
Mitochondria: Make energy out of food
Ribosomes: Make protein
Golgi Apparatus: Make, process and package proteins
Lysosome: Contains digestive enzymes to help break food down
Endoplasmic Reticulum: Called the "intracellular highway" because it is for transporting all sorts of items around the cell.
Vacuole: Used for storage, vacuoles usually contain water or food. (Are you are thirsty? Perhaps your vacuoles need some water!)
Plant cells also have:
Chloroplasts: Use sunlight to create food by photosynthesis
Cell Wall: For support
