cells
what are cells?
The smallest unit that can live on its own and that makes up all living organisms and the tissues of the body
What is the primary pigment involved in photosynthesis?
Chlorophyll
What are the building blocks of proteins
Amino Acids
What is homeostasis?
A state of balance among all the body systems needed for the body to survive and function correctly.
What structure surrounds and protects the cell?
The cell membrane
What are the reactants needed for photosynthesis?
Carbon, Dioxide, and Water
Waht is the main function of carbohydrates in living organisms?
To provide Energy
What is an example of a variable that the body regulates to maintain homeostasis.
Body temperature
What part of the cell contains the genetic material?
Nucleus
What part of the plant does photosynthesis mainly occcur?
In the leaves, specifically in the chloroplasts.
What is the difference between DNA and RNA?
RNA- single-stranded and contains the sugar ribose
DNA- double-stranded and contains sugar deoxyribose
How does the body respond to an increase in temperature?
The sweat cool down and blood vessels in the skin dilate to release heat.
what is the function of ribosomes in a cell?
Carbon dioxide+ Water+ Light energy --> Glucose + Oxygen
What role do enzymes play in biochemical reactions?
They act as a catalysts to speed up chemical reactions without being consumed.
What roles to hormones play in homeostasis?
Hormones act as messengers that helps regulate various body functions, including metabolism, growth, and response to stress.
Describe the process of osmosis and its importance in cells
it controls the cell to cell diffusion of water
what are the 2 main stages of photosynthesis and their functions?
Stage- Light-dependent reactions
Location- Thylakoid membrane
Events- Light energy is captured by chloroplasts and stored as ATP
Stage- Calvin cycle
Location- Stroma
Events- ATP is used to create sugars that the plant will use to grow and live
Explain the process of cellular respiration and its relationship to photosynthesis?
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.
Disrobe the feedback mechanism involved in maintaining blood glucose levels.
negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels
