How do constitutive enzymes differ from inductive enzymes?
Constitutive enzymes are those, which are being synthesized continually, regardless of conditions or demand. Inductive enzymes are those which are not always present and whose synthesis is activated (or induced - hence the name) by certain molecule or compound, often a hormone or even its own substrate. As example of inductive enzyme serves pyruvate carboxylase (enzyme which turns pyruvate into oxalacetate) which is synthesized on demand and the process is activated by cortisol.

What is an enzymes activity is slowed or stopped called?
When an enzyme's activity is slowed or stopped, it is referred to as enzyme inhibition. This can occur through various mechanisms, including competitive inhibition, where an inhibitor competes with the substrate for the active site, or non-competitive inhibition, where the inhibitor binds to a different part of the enzyme, altering its function. Enzyme inhibition can be reversible or irreversible, depending on how the inhibitor interacts with the enzyme.
What does Phosphoglycerate kinase do?
Phosphorylase is an enzyme which joins with Glucose-1-phosphate together to make larger starch molecules. it is an example of synthesis (a joing together enzyme)
What enzyme is needed in order for transcription to take place?
RNA polymerase is the enzyme needed for transcription to take place. It catalyzes the synthesis of an RNA molecule from a DNA template.
What are 5 minerals found in plants?
Iron: important for the formation of chlorophyll and enzyme functions. Calcium: helps with cell wall structure and signaling pathways. Magnesium: critical for photosynthesis and enzyme activation. Phosphorus: essential for energy transfer and DNA/RNA synthesis. Potassium: involved in osmoregulation, enzyme activation, and protein synthesis.
Synthesis of a repressible enzyme is inhibited by?
The corepressor-repressor binding to the operator stops the repressible enzyme synthesis. The rate of production of repressible enzyme can be stopped or inhibited if a substance is in high concentration.
What is the role of a constitutive enzyme in the regulation of metabolic pathways?
A constitutive enzyme is always present and active in a cell, playing a key role in maintaining basic metabolic functions. It helps regulate metabolic pathways by continuously catalyzing specific reactions, ensuring a steady supply of essential molecules for cellular processes.
What is the co enzyme required for fatty acid synthesis?
acetyl CoA or Acetyl Co-enzyme A is required for fatty acid synthesis

What is a constitutive act?
constitutive act
What is enzyme synthesis?
Enzyme synthesis is the process by which cells make enzymes through transcription and translation of the enzyme's gene into a functional protein. This involves the production of mRNA from DNA in the nucleus, and the subsequent translation of this mRNA into the enzyme in the cytoplasm. Enzymes are essential for catalyzing biochemical reactions in cells.
What would be the most likely outcome if the ribosomes of a cell were damaged and stopped functioning?
If ribosomes in a cell were damaged and stopped functioning, protein synthesis would be disrupted. This could lead to a decrease in cell function, impaired growth and development, and ultimately cell death.
What enzyme is responsible for RNA synthesis?
RNA polymerase
How does a constitutive definition differ fron an operational?
constitutive vs operation definition
What does constitutive dimension mean?
Constitutive dimension means the aspect of power that is allotted by the constitution of a government.
Enzyme synthesis in a living cell occurs at which cytoplasmic organelle?
Ribosomes
Synthesis of an inducible enzyme requires?
Substrate bound to a repressor Chris G.
