Enzyme kinetics
In biochemistry, enzymes are proteins that act as biological catalysts. Catalysis is the addition of a catalyst to a chemical reaction to speed up the pace of the reaction. Catalysis can be categorized as either homogeneous or heterogeneous, depending on whether the catalysts are distributed in the same phase as that of the reactants. Enzymes are an essential part of the cell because, without them, many organic processes would slow down and thus will affect the processes that are important for cell survival and sustenance.
Regulation of Enzymes
A substance that acts as a catalyst to regulate the reaction rate in the living organism's metabolic pathways without itself getting altered is an enzyme. Most of the biological reactions and metabolic pathways in the living systems are carried out by enzymes. They are specific for their works and work in particular conditions. It maintains the best possible rate of reaction in the most stable state. The enzymes have distinct properties as they can proceed with the reaction in any direction, their particular binding sites, pH specificity, temperature specificity required in very few amounts.
![by varying amounts of carbon dioxide? We will test this using a virtual
experiment to determine how varying amounts of carbon dioxide
concentration affects the rate of photosynthesis by measuring the amount
of oxygen produced. We will cut an aquatic plant and place it in an inverted
test tube filled with water with a light source shining on the plant. This set
up will allow us to see the plant doing photosynthesis by viewing the oxygen
being released as bubbles in the water. We will collect data by counting
how many bubbles are released in a 2 minute time frame. The more
bubbles released, the higher the rate of photosynthesis. If less bubbles are
released, the rate of photosynthesis is lower.
Hypothesis: If the amount of carbon dioxide is increased, then the rate of photosynthesis
will decrease.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F712dcdfa-8101-4cf1-8df3-4b4baab51edc%2F93e42db3-1074-4bcb-8063-b1c422baa430%2Fk3gnz1m_processed.jpeg&w=3840&q=75)
![Aquatic plants can be used to demonstrate oxygen production in the
process of photosynthesis. In theory, when an aquatic plant is placed in a
solution containing a source of carbon dioxide, in the presence of light, the
plant will photosynthesize and produce bubbles of oxygen-containing gas.
These bubbles can be counted, and the rate of bubbling can serve as an
indication of the rate of photosynthesis. There are several factors that affect
the rate of photosynthesis such as light intensity and carbon dioxide
concentrations. Light is essential for photosynthesis. Green plant cells that
are placed in the dark will not photosynthesize. If the light intensity is
increased, then the rate of photosynthesis should also increase causing a
release of more oxygen bubbles.
Carbon dioxide is also needed for plants to make glucose. We will be
focusing on the effect of carbon dioxide on the rate of photosynthesis. In
this experiment, we will answer the question: How is photosynthesis affected](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F712dcdfa-8101-4cf1-8df3-4b4baab51edc%2F93e42db3-1074-4bcb-8063-b1c422baa430%2Ffyqrb8a_processed.jpeg&w=3840&q=75)
